Airworthiness Directives; General Electric Company Turbofan Engines
Document Number: 2012-31362
Type: Proposed Rule
Date: 2012-12-31
Agency: Federal Aviation Administration, Department of Transportation
We are revising an earlier proposed airworthiness directive (AD) for certain General Electric Company (GE) CF6-80C2 series turbofan engines. That NPRM proposed to supersede an AD that required replacement of fuel tubes connected to the fuel flowmeter. That NPRM was prompted by several reports of fuel leaks, and two reports of engine fire, due to mis-assembled supporting brackets on the fuel tube connecting the flowmeter to the Integrated Drive Generator (IDG) fuel- oil cooler. That NPRM required installation of a new simplified one- piece supporting bracket to eliminate mis-assembly. This supplemental action adds an engine model, alters the list of affected part numbers (P/Ns), changes the replacement schedule, and revises our estimated cost of compliance. We are reopening the comment period to allow the public the opportunity to comment on these proposed changes. We are proposing this AD to prevent high-pressure fuel leaks caused by improper seating of fuel tube flanges, which could result in an engine fire and damage to the airplane.

Type: Rule
Date: 2012-12-31
Agency: Federal Aviation Administration, Department of Transportation
This action amends the emission standards for turbine engine powered airplanes to incorporate the standards promulgated by the United States Environmental Protection Agency (EPA) on June 18, 2012. This amendment fulfills the FAA's requirements under the Clean Air Act Amendments of 1970 to issue regulations ensuring compliance with the EPA standards. This action revises the standards for oxides of nitrogen and test procedures for exhaust emissions based on International Civil Aviation Organization standards, and for the identification and marking requirements for engines.
Airworthiness Directives; GA200 (Pty) Ltd Airplanes
Document Number: 2012-30627
Type: Rule
Date: 2012-12-27
Agency: Federal Aviation Administration, Department of Transportation
We are revising an existing airworthiness directive (AD) for all GA200 (Pty) Ltd Models GA200 and GA200C airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as failure of the wing strut bolt through the main spar. We are issuing this AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
Document Number: 2012-30369
Type: Rule
Date: 2012-12-27
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for all Airbus Model A330-300 series airplanes and Model A340-200 and -300 series airplanes. This AD was prompted by reports that, during a flight test, several spoiler servo-controls (SSCs) did not remain locked in the retracted position (hydraulic locking function) after manual depressurization of the corresponding hydraulic circuit. Loss of that locking functionwhich is ensured by a blocking valvewas caused by an internal leak from a sheared seal on the blocking valve. This AD requires inspecting to determine if certain SSCs are installed, performing an operational test of any affected SSC, and replacing if necessary. We are issuing this AD to prevent loss of the hydraulic locking function during take-off and go-around phases, which, in combination with malfunction of one engine, could result in reduced controllability of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-29999
Type: Rule
Date: 2012-12-27
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This AD was prompted by reports of escape slides failing to deploy from the forward and aft right-hand doors during scheduled maintenance slide deployments. This AD requires modifying the escape slide. Also, for certain airplanes, this AD requires modifying or replacing the Vespel piston. For certain other airplanes, this AD requires an additional modification of the escape slide. We are issuing this AD to prevent failure of an escape slide to deploy, which could result in the slide being unusable during an emergency evacuation and increased likelihood of injury to passengers or crewmembers due to the difficulty in evacuating the airplane.
Airworthiness Directives; Gulfstream Aerospace Corporation
Document Number: 2012-31036
Type: Proposed Rule
Date: 2012-12-26
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation Model GV and GV-SP airplanes. This proposed AD was prompted by reports of two failures of the fuel boost pump and over-heat damage found on the internal components and external housing. This proposed AD would require doing an inspection to determine if fuel boost pumps having a certain part number are installed, replacing the fuel boost pumps having a certain part number, and revising the airplane maintenance program to include revised instructions for continued airworthiness. We are proposing this AD to prevent fuel leakage into the dry cavity of the boost pump and outside of the fuel pump, and to prevent capacitor clearance issues in the dry cavity, which together could result in an uncontrolled fire in the wheel well.
Airworthiness Directives; Bombardier, Inc. Airplanes
Document Number: 2012-30925
Type: Proposed Rule
Date: 2012-12-26
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-102, -103, and -106 airplanes, and Model DHC-8-200, -300, and -400 series airplanes. This proposed AD was prompted by reports of excessive wear found in the clevis (bolt) hole where the rod assembly attaches to the rudder/brake pedal bellcrank, due to prolonged fretting. This proposed AD would require measuring the bellcrank clevis holes, inspecting for cracking of the bellcrank, and re-working the clevis holes with steel bushings, or replacing the bellcrank. We are proposing this AD to detect and correct a worn or cracked clevis hole, which could cause failure of the bellcrank on one side, with subsequent asymmetric braking and consequent runway excursion.
Airworthiness Directives; Embraer S.A. Airplanes
Document Number: 2012-30916
Type: Proposed Rule
Date: 2012-12-26
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede an existing airworthiness directive (AD) that applies to certain Embraer S.A. Model ERJ 170 and ERJ 190 airplanes. The existing AD currently requires, for certain airplanes, repetitively replacing the low-stage check valve and associated seals of the right hand (RH) engine's engine bleed system with a new check valve and new seals, replacing the low pressure check valves (LPCV), and revising the maintenance program. For certain other airplanes, the existing AD requires replacing a certain low-stage check valve with an improved low-stage check valve. Since we issued that AD, we have received reports of uncommanded engine shutdowns on both Model ERJ 170 and ERJ 190 airplanes due to excessive wear and failure of LPCVs having certain part numbers. This proposed AD would also, for certain airplanes, require replacing certain LPCVs of the left-hand (LH) and RH engines, which would be an option for other airplanes. We are proposing this AD to prevent the possibility of a dual engine in-flight shutdown due to LPCV failure.

Type: Rule
Date: 2012-12-26
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for all Airbus Model A330-200 and -300 series airplanes. This AD was prompted by a report of a prematurely fractured main landing gear (MLG) bogie beam. This AD requires replacing certain MLG bogie beams before reaching new reduced life limits. We are issuing this AD to prevent fracture of the MLG bogie beam, which, under high speed, could ultimately result in the airplane departing the runway, the bogie beam detaching from the airplane, or collapse of the MLG; and consequent structural damage to the airplane and injury to the occupants.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-30305
Type: Rule
Date: 2012-12-26
Agency: Federal Aviation Administration, Department of Transportation
We are superseding an existing airworthiness directive (AD) for certain The Boeing Company Model 757-200, -200CB, and -300 series airplanes. That AD currently requires initial and repetitive inspections of the fuselage skin and bear strap at the forward, upper corner of the L1 entry door cutout for cracking, and repair if necessary. That action also provides an optional terminating action for the repetitive inspections. That AD also requires additional inspections for airplanes having repairs or preventative modifications installed and inspections for certain other airplanes. This AD requires the previous actions with additional airplane group configurations added to paragraph (n) of this AD. This AD was prompted by a determination that certain airplane group configurations in paragraph (n) of the existing AD were inadvertently removed in the final rule. We are issuing this AD to detect and correct cracking of the fuselage skin and bear strap at the forward upper corner of the L1 entry door cutout, which could result in reduced structural integrity of the L1 entry door, and consequent rapid decompression of the airplane.

Airworthiness Directives; Cessna Aircraft Company Airplanes
Document Number: 2012-30753
Type: Proposed Rule
Date: 2012-12-21
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) (previously COLUMBIA or LANCAIR) Models LC40-550FG, LC41-550FG, and LC42-550FG airplanes. This proposed AD was prompted by reports that during maximum braking, if the brakes lock up and a skid occurs, a severe oscillatory yawing motion or ``wheel walk'' may develop, which could result in further significant structural damage to the airplane. This proposed AD would require insertions into the pilot's operating handbook (POH) and the airplane maintenance manuals (AMM) regarding proper use of the brakes and inspection of the aft fuselage. We are proposing this AD to correct the unsafe condition on these products.

Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-30666
Type: Proposed Rule
Date: 2012-12-20
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 757 and Model 767 airplanes. This proposed AD was prompted by a standby power relay failure and subsequent illumination of the ``STANDBY BUS OFF'' light, which led the flightcrew to set the standby power switch to the ``BAT'' position, isolating the battery and standby buses, disabling the battery charger, and eventually causing the main battery to be depleted. This proposed AD would require doing wiring changes and installing a new air/ground relay to the battery charger system. We are proposing this AD to prevent discharge of the main battery, which could result in multiple system degradation, reduced airplane controllability, and runway excursion upon landing.

The National Parks Air Tour Management Act (NPATMA) requires the Federal Aviation Administration (FAA) and National Park Service (NPS) to develop an air tour management plan for units of the national park system where an operator has requested authority to provide commercial air tours. The FAA Modernization and Reform Act of 2012 amended various provisions of NPATMA. One provision exempted national park units with 50 or fewer annual flights from the provisions of NPATMA and requires FAA and NPS to jointly publish a list of exempt parks. This notice includes an initial list of parks that are exempt from the provisions of the NPATMA.
Special Conditions: Embraer S.A., Model EMB-550 Airplanes; Electrical/Electronic Equipment Bay Fire Detection and Smoke Penetration
Document Number: 2012-30493
Type: Proposed Rule
Date: 2012-12-19
Agency: Federal Aviation Administration, Department of Transportation
This action proposes special conditions for the Embraer S.A. Model EMB-550 airplane. This airplane will have novel or unusual design features, specifically distributed electrical and electronic equipment bays in pressurized areas of the airplane. Older transport category airplane electrical/electronic equipment bay installations are located in the lower lobe where the flightcrew could determine the origin of smoke or fire by a straightforward airplane flight manual procedure. In distributed electrical/electronic bay installations it is not as straightforward. The FAA has no requirement for smoke and/or fire detection in the electrical/electronic equipment bays. To ensure effective mitigation of fires, the FAA proposes these special conditions. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

Airworthiness Directives; Embraer S.A. Airplanes
Document Number: 2012-30368
Type: Proposed Rule
Date: 2012-12-17
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 190 airplanes. This proposed AD was prompted by reports of cracks on the side stay of the main landing gear (MLG). This proposed AD would require repetitive measurements of the left-hand (LH) and right-hand (RH) MLG side stay support fitting to detect bushing migration, replacement of the bushing if necessary, and eventual replacement of the bushing; a detailed inspection for damage on the LH and RH MLG side stay support assembly, and related investigative and corrective actions if necessary. We are proposing this AD to prevent excessive bearing friction, which might compromise the MLG free fall extension, and cause fatigue cracking on the MLG side stay and on its support assembly, resulting in reduced structural integrity of the MLG.
Airworthiness Directives; Gulfstream Aerospace Corporation Airplanes
Document Number: 2012-30058
Type: Rule
Date: 2012-12-17
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation Model GIV-X airplanes. This AD requires performing a modified system power-on self test (SPOST) of the flap/stabilizer electronic control unit (FSECU), and revising the airplane flight manual to incorporate these test procedures into the daily preflight check. This AD was prompted by reports indicating that the FSECU does not detect failures of the brake feature within the horizontal stabilizer electric motor unit (HSEMU), or failures of drive solenoids for hydraulic valves within the flap hydraulic control module (FHCM) during the SPOST. We are issuing this AD to detect and correct such failures, which could result in runaway horizontal stabilizer pitch trim system and consequent loss of pitch control.
Airworthiness Directives; General Electric Company Turbofan Engines
Document Number: 2012-30072
Type: Proposed Rule

Type: Rule
Date: 2012-12-12
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 757 airplanes. This AD was prompted by a report of in-flight fracture of the right windshield (window 1) on the flight deck and multiple reports of electrical arcs at the terminal blocks of the flight deck windshields resulting in smoke and fire. This AD requires repetitive inspections of electrical heat terminals on the left and right windshields for damage, and corrective actions if necessary. This AD allows replacing an affected windshield with a windshield equipped with different electrical connections, which would terminate the repetitive inspections for that windshield. We are issuing this AD to prevent smoke and fire in the flight deck, which can lead to loss of visibility, and injuries to or incapacitation of the flightcrew.
Airworthiness Directives; Bombardier, Inc. Airplanes
Document Number: 2012-29708
Type: Rule
Date: 2012-12-12
Agency: Federal Aviation Administration, Department of Transportation
We are superseding an existing airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. That AD currently requires revising the airworthiness limitations section (AWL) of the Instructions for Continued Airworthiness (ICA) of the Canadair Regional Jet Maintenance Requirements Manual (MRM) by incorporating new procedures for repetitive detailed and special detailed inspections for cracking of the aft pressure bulkhead. This new AD requires revising the maintenance program to incorporate a revised task specified in a certain temporary revision, which requires an improved non-destructive inspection procedure; and adds airplanes to the applicability. This AD was prompted by multiple reports of cracks on the forward face of the rear pressure bulkhead (RPB) web. We are issuing this AD to detect and correct cracking in the RPB, which could result in reduced structural integrity and rapid decompression of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-29707
Type: Rule
Date: 2012-12-12
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-400 and -400F series airplanes. This AD was prompted by multiple reports of integrated display unit (IDU) malfunctions and mode control panel (MCP) malfunctions. This AD requires installing new software, replacing the duct assembly with a new duct assembly, making wiring changes, and routing certain wire bundles. We are issuing this AD to prevent IDU malfunctions, which could affect the ability of the flightcrew to read primary displays for airplane attitude, altitude, or airspeed, and consequently reduce the ability of the flightcrew to maintain control of the airplane.
Airworthiness Directives; Agusta S.p.A. Helicopters
Document Number: 2012-28432
Type: Rule
Date: 2012-12-12
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model A109E and Model A109S helicopters with certain lower semichannel assemblies installed. This AD requires a one-time inspection of the lower semichannel assemblies to determine if metallic spacers are installed. If the metallic spacers are installed, this AD requires an inspection for the correct installation of the metallic spacers on the semichannels and for the correct seating of the gaskets. If the metallic spacers are not installed with rivets, the lower semichannel assemblies must be modified, and the main drive shaft must be inspected for damage. This AD was prompted by reports of damage to the main drive shaft caused by improperly secured metallic spacers on some A109 model helicopters. The actions of this AD are intended to detect missing spacer rivets, which could allow the metallic spacers to rotate and lead to damage and failure of the main drive shaft, and subsequent loss of helicopter control.
Airworthiness Directives; Turbomeca S.A. Turboshaft Engines
Document Number: 2012-29871
Type: Proposed Rule
Date: 2012-12-11
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Turbomeca S.A. Arriel 1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 1E2, 1K1, 1S, and 1S1 turboshaft engines. This proposed AD was prompted by a finding that the engine's tachometer unit cycle counting feature is unreliable. This proposed AD would require daily post-flight checks of the engine tachometer's unit cycle counting feature. This proposed AD would also require ground-run functional checks within every 1,000 operating hours. This proposed AD was prompted by detailed analysis and review of the accuracy of the engine's tachometer cycle counting feature. We are proposing this AD to prevent uncontained engine failure and damage to the helicopter.
Airworthiness Directives; Agusta S.p.A. (Type Certificate Currently Held by AgustaWestland S.p.A.) (Agusta) Helicopters

Agency: Federal Aviation Administration, Department of Transportation
We are publishing a new airworthiness directive (AD) for Agusta Model AW139 helicopters, which was sent previously to all known U.S. owners and operators of these helicopters. This AD requires inspecting the pilot's and co-pilot's collective and cyclic control sticks for correctly installed attaching hardware. This AD is prompted by a report of an incorrectly installed pilot's collective stick, pilot's cyclic stick, and co-pilot's cyclic stick. These actions are intended to prevent detachment of the cyclic or collective control stick, and subsequent loss of control of the helicopter.
Airworthiness Directives; Airbus Airplanes
Document Number: 2012-29713
Type: Proposed Rule
Date: 2012-12-10
Agency: Federal Aviation Administration, Department of Transportation
We are revising an earlier proposed airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. That supplemental notice of proposed rulemaking (SNPRM) proposed an inspection to determine if certain angle of attack (AOA) probes are installed, and replacement of any affected AOA probe. That SNPRM was prompted by reports of oil residue between the stator and the rotor parts of the position resolvers of the AOA vane, which was a result of incorrect removal of the machining oil during the manufacturing process of the AOA resolvers. This action revises that SNPRM by clarifying the affected parts. We are proposing this AD to prevent erroneous AOA information and consequent delayed or non-activation of the AOA protection systems which, during flight at a high angle of attack, could result in reduced control of the airplane. Since these actions impose an additional burden over that proposed in the SNPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
Airworthiness Directives; Airbus Airplanes
Document Number: 2012-29710
Type: Proposed Rule
Date: 2012-12-10
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300- 600 series airplanes); and Model A310 series airplanes. This proposed AD was prompted by a report of an uncommanded slide back of the co- pilot seat to the end stop position. This proposed AD would require a one-time inspection for a part number, a tensile test of the affected seats, and corrective actions if necessary. We are proposing this AD to detect and prevent unwanted movement of a pilot or co-pilot seat in the horizontal direction, which could lead to inadvertent input on the flight control commands and possibly result in loss of controllability of the airplane.
Clarification of Wildlife Hazard Management Requirements for Non-Certificated Federally Obligated Airports in the National Plan of Integrated Airport Systems (NPIAS)
Document Number: 2012-29591
Type: Notice
Date: 2012-12-10
Agency: Federal Aviation Administration, Department of Transportation
To enhance safety, the FAA proposes to clarify Grant Assurance No. 19, ``Operation and Maintenance,'' which is required of an airport sponsor as a condition of receiving a development grant under the Airport Improvement Program (AIP). This clarification would require non-certificated, federally obligated airports that, after the effective date of this Federal Register Notice, accept a new airport development grant funded under the Airport Improvement Program (AIP), or accept a transfer of land under the Surplus Property Act for airport purposes (``Subject Airports''), to conduct Wildlife Hazard Site Visits (WHSVs) or Wildlife Hazard Assessments (WHAs). Non-certificated airports are airports that do not have a Part 139 certificate, and may include both commercial service airports as well as non-primary airports that serve mostly general aviation traffic. The Secretary of Transportation is required to provide notice and comment in the Federal Register and an opportunity for the public to comment upon proposals to modify the assurances or add new assurances.
Airworthiness Directives; Rolls-Royce plc Turbofan Engines
Document Number: 2012-29489
Type: Rule
Date: 2012-12-10
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Rolls-Royce plc (RR) RB211-Trent 900 series turbofan engines. This AD requires inspection of the low pressure turbine (LPT) bearing housing end cover assembly in certain engines and, if necessary, its replacement. This AD was prompted by a Trent 900 engine experiencing a high intermediate pressure vibration fault, along with other fluctuating engine parameters, while in flight. We are issuing this AD to prevent fracture of the oil transfer tube, which could result in uncontained failure of the engine and damage to the airplane.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-29469
Type: Rule
Date: 2012-12-10
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This AD was prompted by reports of flight crew failure to activate air data probe heat. This AD requires modifying the anti-icing system for the angle of attack sensor, the total air temperature, and the pitot probes. We are issuing this AD to prevent ice from forming on air data system sensors and consequent loss of or misleading airspeed indication on all airspeed indicating systems, which could lead to loss of control of the airplane.
Airworthiness Directives; Saab AB, Saab Aerosystems Airplanes
Document Number: 2012-29169
Type: Rule
Date: 2012-12-10
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Saab AB, Saab Aerosystems Model 340A (SAAB/SF340A) and SAAB 340B airplanes. This AD was prompted by reports of stall events during icing conditions where the natural stall warning (buffet) was not identified. This AD requires replacing the stall warning computer (SWC) with a new SWC, which provides an artificial stall warning in icing conditions, and modifying the airplane for the replacement of the SWC. We are issuing this AD to prevent natural stall events when operating in icing conditions, which, if not corrected, could result in loss of control of the airplane.
Airworthiness Directives; Erickson Air-Crane Incorporated Helicopters
Document Number: 2012-28434
Type: Rule
Date: 2012-12-10
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for Erickson Air-Crane Incorporated (Erickson) Model S-64F helicopters. This AD requires inspecting for cracking or working rivets in each left and right splice fitting (transition fitting), the pylon bulkhead assembly-canted (bulkhead assembly), and the pylon steel strap (strap). This AD was prompted by several reports of cracking in the transition fittings, the bulkhead assembly, and the pylon. The actions specified by this AD are intended to detect cracking in the rotary rudder boom or pylon due to fatigue, and to prevent failure from static overload and subsequent loss of control of the helicopter.
Airworthiness Directives; Embraer S.A. Airplanes
Document Number: 2012-28173
Type: Rule
Date: 2012-12-10
Agency: Federal Aviation Administration, Department of Transportation
We are superseding an existing airworthiness directive (AD) for all Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. That AD currently requires revising the maintenance program to incorporate modifications in the Airworthiness Limitation Section (ALS) of the EMBRAER ERJ 190 Maintenance Review Board Report (MRBR). This new AD requires revising the maintenance program to incorporate modifications in the ALS of the EMBRAER ERJ 190 MRBR to include new inspection tasks and their respective thresholds and intervals. This AD was prompted by issuance of new inspection tasks and their respective thresholds and intervals. We are issuing this AD since failure to inspect these structural components according to the new ALS tasks, thresholds, and intervals could prevent a timely detection of fatigue cracking, which if not properly addressed, could result in reduced structural integrity of the airplane.
