Airworthiness Directives; Pratt & Whitney JT8D-209, -217, -217C, and -219 Turbofan Engines
The FAA proposes to revise an existing airworthiness directive (AD) for Pratt & Whitney JT8D-209, -217, -217C, and -219 turbofan engines with front compressor front hub (fan hub), part number (P/N) 5000501-01 installed. That AD currently requires cleaning the front compressor front hubs (fan hubs), initial and repetitive eddy current (ECI) and fluorescent penetrant inspections (FPI) of tierod and counterweight holes for cracks, removal of bushings, cleaning and ECI and FPI of bushed holes for cracks and, if necessary, replacement with serviceable parts. In addition, that AD currently requires reporting the findings of cracked fan hubs and monthly reports of the number of inspections completed. This proposed AD would require the same actions, except for the monthly reporting of the number of completed inspections. This proposed AD results from the FAA determining that it has collected a sufficient amount of data since issuing AD 97-17-04 and that therefore, it no longer needs the monthly reporting of the number of completed inspections. We are proposing this AD revision to prevent fan hub failure due to tierod, counterweight, or bushed hole cracking, which could result in an uncontained engine failure and damage to the airplane.
Airworthiness Directives; Honeywell International LTS101-600A Series and LTS101-700D-2 Turboshaft Engines and LTP101-600A-1A, and LTP101-700A-1A Turboprop Engines
The FAA proposes to adopt a new airworthiness directive (AD) for Honeywell International LTS101-600A series and LTS101-700D-2 turboshaft engines and LTP101-600A-1A, and LTP101-700A-1A turboprop engines with power turbine blades, part number (P/N) 4-141-084-06, installed. This proposed AD would require removing power turbine blades, P/N 4-141-084-06 from service, using a drawdown schedule specified in this proposed AD. This proposed AD results from reports of fatigue cracks in the airfoil of the power turbine blade. We are proposing this AD to prevent fracture of the power turbine blade airfoil, which could result in sudden loss of engine power.
Airworthiness Directives; CFM International, S.A. CFM56-5B1/P, -5B2/P, -5B3/P, -5B3/P1, -5B4/P, -5B5/P, -5B6/P, -5B7/P, -5B8/P, -5B9/P, -5B1/2P, -5B2/2P, -5B3/2P, -5B3/2P1, -5B4/2P, -5B4/P1, -5B6/2P, -5B4/2P1, and -5B9/2P Turbofan Engines
The FAA proposes to supersede an existing airworthiness directive (AD) for CFM International, S.A. CFM56-5B series turbofan engines. That AD currently requires reviewing exhaust gas temperature (EGT) monitoring records to determine EGT margin deterioration, and for airplanes where both engines have greater than 80 [deg]centigrade (C) of EGT margin deterioration, borescope-inspecting the high-pressure compressor (HPC) of both engines. That AD also currently requires removing from service any engine that does not pass the borescope inspection and, if both engines pass, removing and replacing one of the engines with an engine that has 80 [deg]C or less of EGT margin deterioration. That AD also currently requires continuous monitoring of EGT margin deterioration on engines in service to prevent two engines on an airplane from having greater than 80 [deg]C of EGT margin deterioration. This proposed AD would require continuous monitoring of EGT margin deterioration, removing FADEC software version 5.B.Q and earlier versions from the engine as mandatory terminating action to the repetitive recalculating and EGT monitoring for certain engine models, and removing other certain engine models from service if the EGT margin deterioration is greater than 75 [deg]C. This proposed AD results from the need to reduce the affected engine models listed in AD 2009-01-01 from 25 to 19, the need to reduce the engine EGT margin deterioration removal threshold from greater than 80 [deg]C to greater than 75 [deg]C, the need to mandate a terminating action to the repetitive recalculating and EGT monitoring for certain engines, and the need to remove certain engines from service if the EGT margin deterioration is greater than 75 [deg]C. We are proposing this AD to prevent HPC stalls, which could prevent continued safe flight or landing.

Airworthiness Directives; Hawker Beechcraft Corporation Model G58 Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Model G58 airplanes. This proposed AD would require inspecting the installation of stand-off hardware between the heater fuel line and the heater over-temperature sensor wires for minimum clearance and installing acceptable stand-off hardware if stand-off hardware is missing or inadequate. This proposed AD would also require inspecting the brake reservoir line and the fuel heater power wire for damage and minimum clearance, replacing any damaged wires and/or lines, and installing stand-off hardware if minimum clearance is not met. This proposed AD results from reports received of a power wire shorting out on the brake reservoir tube. We are proposing this AD to detect and correct inadequate clearance of the brake reservoir tubing and the heater fuel pump wiring, which could result in chafing and shorting out of the electrical wiring and chafing of the tubing carrying flammable fluids. This condition could lead to a fire in the nose wheel well.
Airworthiness Directives; Cessna Aircraft Company (Type Certificate Previously Held by Columbia Aircraft Manufacturing (Previously The Lancair Company)) Models LC40-550FG, LC41-550FG, and LC42-550FG Airplanes
We propose to supersede Airworthiness Directive (AD) 2009-09- 09, which applies to certain Cessna Aircraft Company (Cessna) (type certificate previously held by Columbia Aircraft Manufacturing (previously The Lancair Company)) Models LC40-550FG, LC41-550FG, and LC42-550FG airplanes. AD 2009-09-09 currently requires repetitive inspections of the rudder hinges and the rudder hinge brackets for damage, i.e., cracking, deformation, and discoloration. If damage is found during any inspection, AD 2009-09-09 also requires replacing the damaged rudder hinge and/or rudder hinge bracket. Since we issued AD 2009-09-09, Cessna has developed a modification that, when incorporated, would terminate the repetitive inspections required by AD 2009-09-09. The FAA has determined that long-term continued operational safety will be better assured by design changes that removed the source of the problem, rather than by repetitive inspections or other special procedures. Consequently, this proposed AD would retain the inspection requirements of AD 2009-09-09 and add a terminating action for the inspection requirements. We are proposing this AD to detect and correct damage in the rudder hinges and the rudder hinge brackets, which could result in failure of the rudder. This failure could lead to loss of control.
Airworthiness Directives; Hawker Beechcraft Corporation (Type Certificate Previously Held by Raytheon Aircraft Company) Models B300 and B300C Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation (type certificate previously held by Raytheon Aircraft Company) Models B300 and B300C airplanes. This proposed AD would require you to inspect the terminal board on the circuit card rack assembly to determine if the correct bus bar is installed. This proposed AD would also require you to replace the bus bar if necessary and inspect the left and right pitot heat annunciators for proper operation. This proposed AD results from reports of the left and right pitot heat annunciators not illuminating for an inoperative pitot heat condition. We are proposing this AD to detect and correct installation of an incorrect bus bar, which could result in failure of the pitot heat annunciators to illuminate. This failure could lead to the pilot being unaware that moisture has frozen on the pitot tube(s) and cause erroneous flight instrument indication.

No program elements relating to new or revised flight procedures for noise abatement were proposed by the airport operator.
Airworthiness Directives; The Boeing Company Model 727 Airplanes
The FAA is revising an existing airworthiness directive (AD), which applies to all The Boeing Company Model 727 airplanes. That AD currently requires revising the FAA-approved maintenance program by incorporating new airworthiness limitations (AWLs) for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. That AD also requires an initial inspection to phase in a certain repetitive AWL inspection, and repair if necessary. This AD clarifies the intended effect of the AD on spare and on-airplane fuel tank system components. This AD results from a design review of the fuel tank systems. We are issuing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
Notice of Passenger Facility Charge (PFC) Approvals and Disapprovals
The FAA publishes a monthly notice, as appropriate, of PFC approvals and disapprovals under the provisions of the Aviation Safety and Capacity Expansion Act of 1990 (Title IX of the Omnibus Budget Reconciliation Act of 1990) (Pub.

Airworthiness Directives; Cirrus Design Corporation Model SR22 Airplanes
We are adopting a new airworthiness directive (AD) for certain Cirrus Design Corporation Model SR22 airplanes equipped with an anti- ice system approved for flight into known icing. This AD requires you to inspect the compression fittings on the anti-ice fluid distribution lines for proper installation and repair any fittings that were not properly installed. This AD results from the manufacturer finding some anti-ice fluid distribution lines where the compression fittings were not properly installed. We are issuing this AD to detect and correct anti-ice fluid distribution lines with improperly installed compression fittings, which could result in anti-ice fluid distribution line separation. A line separation could result in a total loss of ice protection fluid supply to the protected surfaces, which would allow ice to build on the airplane and degrade the handling qualities and performance.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135BJ, -135ER, -135KE, -135KL, -135LR, -145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated 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:
Airworthiness Directives; General Electric Company CF6-80C2 Series Turbofan Engines; Correction
The FAA is correcting airworthiness directive (AD) 2009-21-07, which published in the Federal Register. That AD applies to General Electric Company (GE) CF6-80C2 series turbofan engines with certain thrust reverser ballscrew gearbox assembly adjustable-length end actuators installed. The unsafe condition statement of ``We are issuing this AD to prevent loss of asymmetric thrust and thrust control'', and rod-end part number ``MS2124S06'' in paragraph (j) are incorrect. This document corrects the unsafe condition statement and the part number. In all other respects, the original document remains the same.
Airworthiness Directives; General Electric Company GE90-110B1, GE90-113B, and GE90-115B Series Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for General Electric Company (GE) GE90-110B1, GE90-113B, and GE90-115B series turbofan engines with stage 6 low-pressure turbine (LPT) blades, part number (P/N) 1765M37P03 or P/N 1765M37P04, installed. This AD requires initial and repetitive inspections for shroud interlock wear of the stage 6 LPT blades. This AD also requires replacing those blades with stage 6 LPT blades eligible for installation at the next engine shop visit as terminating action to the repetitive blade inspections. This AD results from eight reports of GE90-115B stage 6 LPT single-blade separation events. We are issuing this AD to prevent failure of stage 6 LPT blades, which could result in uncontained engine failure and damage to the airplane.
Airworthiness Directives; Eurocopter France Model SA 330 F, G, and J Helicopters
We are adopting a new airworthiness directive (AD) for the specified Eurocopter France (Eurocopter) helicopters. This AD results from a mandatory continuing airworthiness information (MCAI) AD issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community. The MCAI Emergency AD states that there has been a report of the failure of a flexible coupling on one of the main gearbox (MGB) inputs, which may be the result of loss of the tightening torque load, or insufficient tightening of the nuts on the bolts fixing the discs of the flexible coupling to its sliding and fixed hinges. This condition, if not corrected, could result in failure of the coupling discs, and if this condition develops on both the left-hand (LH) and right-hand (RH) MGB inputs, a complete loss of power to the transmission and subsequent loss of control of the helicopter.
Airworthiness Directives; Eurocopter France (ECF) Model AS332C, AS332L, AS332L1, AS332L2, SA330F, SA330G, and SA330J Helicopters
We are adopting a new airworthiness directive (AD) for the specified ECF helicopters. This AD results from a mandatory continuing airworthiness information (MCAI) AD issued by the European Aviation Safety Agency (EASA), the Technical Agent for the aviation authority of France. The MCAI AD states there have been two cases of failure of the screw that secures the main rotor blade (blade) deicing system distributor retaining clamp (clamp). Analysis revealed that these failures were the result of insufficient clearance of the screw and the clamp assembly causing the screw to bend and also by some screws having nonconforming material hardness. Also, some of the screw heads were missing a lock-wiring hole preventing the use of lock-wiring between the screw head and the nut.
Random Drug and Alcohol Testing Percentage Rates of Covered Aviation Employees for the Period of January 1, 2010, Through December 31, 2010
The FAA has determined that the minimum random drug and alcohol testing percentage rates for the period January 1, 2010, through December 31, 2010, will remain at 25 percent of safety- sensitive employees for random drug testing and 10 percent of safety- sensitive employees for random alcohol testing.
Airworthiness Directives; Airbus Model A300 B2-1C, B2K-3C, B2-203, B4-2C, B4-103, and B4-203 Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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: One operator reported loss of both pitch trims following autopilot disengagement after take off. Subsequent shop findings revealed severe damage to the power gears. Mal-phasing between the hydraulic motors was suspected to have induced excessive loads into the gear train, leading to collapse of one bearing on a shaft of the main gear, causing severe tooth damage. The combination of tooth damage and gear tilting caused the disconnection of two of the three hydraulic motors, resulting in jamming of the THSA [Trimmable Horizontal Stabilizer Actuator] gearbox and consequent loss of THSA control. This condition, if not detected and corrected, could lead to further cases of mal-phasing of the hydraulic motors of the THSA, causing degradation of the power gears and potentially resulting in reduced control of the aeroplane. The proposed AD would require actions that are intended to
Airworthiness Directives; Honeywell International Inc. TFE731 Series Turbofan Engines
This supplemental NPRM revises an earlier proposed airworthiness directive (AD), for Honeywell International Inc. TFE731 series turbofan engines with certain second stage low-pressure compressor rotor (LPCR) discs and/or certain third stage LPCR discs installed. That proposed AD would have required removing from service certain second stage LPCR discs and/or certain third stage LPCR discs. That proposed AD resulted from a report of cracks found during a fluorescent penetrant inspection (FPI) of the disc bore. This supplemental NPRM revises the proposed AD to correct a P/N error, to clarify the applicability, and to clarify the instructions in the compliance section. This supplemental proposed AD results from a report of cracks found during an FPI of the disc bore. We are proposing this supplemental proposed AD to prevent an uncontained failure of a second stage LPCR disc and or a third stage LPCR disc due to cracks in the bore, which could result in damage to the airplane.
