Federal Aviation Administration June 21, 2006 – Federal Register Recent Federal Regulation Documents

Special Conditions: Boeing Model 777-200 Series Airplanes; Forward Lower Lobe Crew Rest Compartment (CRC)
Document Number: E6-9819
Type: Proposed Rule
Date: 2006-06-21
Agency: Federal Aviation Administration, Department of Transportation
This action proposes special conditions for the Boeing Model 777-200 series airplanes. These airplanes, modified by Aerocon Engineering Company (AEC), will have a novel or unusual design feature associated with a forward lower lobe crew rest compartment (CRC). 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.
Special Conditions; Rickenbacker Avionics, EFS-50 EFIS Installation in Rockwell Twin Commander Model 690B; Protection of Systems From High Intensity Radiated Fields (HIRF)
Document Number: E6-9818
Type: Rule
Date: 2006-06-21
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued to Rickenbacker Avionics, 2820 Bobmeyer Road, Hangar C-6, Hamilton, OH 45015, for a Supplemental Type Certificate for the Rockwell Twin Commander Model 690B airplane. This airplane will have novel and unusual design features when compared to the state of technology envisaged in the applicable airworthiness standards. This novel and unusual design feature will include the installation of a two-tube Bendix/King EFS-50 Electronic Flight Instrument System (EFIS). The installation also includes components associated with this display system. The applicable regulations do not contain adequate or appropriate airworthiness standards for the protection of these systems from the effects of high intensity radiated fields (HIRF). These 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 the airworthiness standards applicable to these airplanes.
Disqualification for Airman and Airman Medical Certificate Holders Based on Alcohol Violations or Refusals To Submit to Drug and Alcohol Testing
Document Number: E6-9814
Type: Rule
Date: 2006-06-21
Agency: Federal Aviation Administration, Department of Transportation
This final rule changes the airman medical certification standards to disqualify an airman based on an alcohol test result of 0.04 or greater breath alcohol concentration (BAC) or a refusal to take a drug or alcohol test required by the Department of Transportation (DOT) or a DOT agency. Further, this rulemaking standardizes the time period for reporting refusals and certain test results to the FAA, and requires employers to report pre-employment and return-to-duty test refusals. It also amends the airman medical certification requirements to allow suspension or revocation of airman medical certificates for pre-employment and return-to-duty test refusals. Finally, we have updated the regulations to recognize current breath alcohol testing technology. These amendments are necessary to ensure that persons who engage in substance abuse do not operate aircraft or perform contract air traffic control duties until it is determined that these individuals can safely exercise the privileges of their certificates.
Airworthiness Directives; Boeing Model 747 Airplanes
Document Number: E6-9721
Type: Proposed Rule
Date: 2006-06-21
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Boeing Model 747 airplanes. The existing AD currently requires a one-time inspection to determine whether the outer cylinder of the wing landing gear has certain part numbers (P/Ns), and replacement of the outer cylinder of the wing landing gear with a new, improved, or reworked part if necessary. The existing AD also requires removal of the load evening system, if such a system is installed. For certain airplanes, this proposed AD would require an additional one-time inspection to determine whether the outer cylinder has a certain other P/N. For those certain airplanes, this proposed AD would also require replacement of the outer cylinder with a reworked or new, improved part and related investigative/ corrective actions, if necessary. This proposed AD results from identification of an additional unsafe part. We are proposing this AD to prevent fracture of the outer cylinder of the wing landing gear, which could result in collapse of the wing landing gear.
Airworthiness Directives; McDonnell Douglas Model MD-11 and -11F Airplanes
Document Number: E6-9718
Type: Proposed Rule
Date: 2006-06-21
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain McDonnell Douglas Model MD-11 and -11F airplanes. The existing AD currently requires an initial general visual inspection of the power feeder cables of the integrated drive generator (IDG) and the fuel feed lines of engine pylons No. 1 and No. 3 on the wings for proper clearance and damage; corrective actions if necessary; and repetitive general visual inspections and a terminating action for the repetitive inspections. This proposed AD would continue to require the existing actions, and for certain airplanes, this proposed AD would require installation of new clamps on the power feeder cables of the IDG of engine pylons No. 1 and No. 3. This proposed AD results from reports of IDG power feeder cables riding against structure and fuel lines in the No. 1 and No. 3 pylons. We are proposing this AD to prevent potential chafing of the power feeder cables of the IDG in engine pylons No. 1 and No. 3 on the wings, and consequent arcing on the fuel lines in the engine pylons and possible fuel fire.
Airworthiness Directives; Airbus Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model A300 C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes)
Document Number: E6-9715
Type: Proposed Rule
Date: 2006-06-21
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Airbus Model A300-600 series airplanes. The existing AD currently requires an inspection for evidence of chafing between the hydraulic flexible hose and the ram air turbine (RAT) hub, and related investigative and corrective actions if necessary. This proposed AD would extend the applicability to include all A300-600 series airplanes that are equipped with a certain RAT. This proposed AD results from reports of holes in the RAT hub cover. We are proposing this AD to prevent a hole in the RAT hub cover. A hole in the RAT hub cover could allow water to enter the RAT governing mechanism, freeze during flight, and jam the governing mechanism. In addition, the metal particles that result from chafing between the hydraulic flexible hose and the RAT could mix with the lubricant grease and degrade the governing mechanism. In an emergency, a jammed or degraded RAT could result in its failure to deploy, loss of hydraulic pressure or electrical power to the airplane, and consequent reduced controllability of the airplane.
Airworthiness Directives; Fokker Model F27 Mark 500 Airplanes
Document Number: E6-9714
Type: Proposed Rule
Date: 2006-06-21
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for all Fokker Model F27 Mark 500 airplanes. This proposed AD would require an inspection to determine whether certain main landing gear (MLG) drag stay units (DSUs) are installed. This proposed AD would also require an ultrasonic inspection to determine if certain tubes are installed in the affected DSUs of the MLG, and related investigative/ corrective actions if necessary. This proposed AD results from a report that, due to fatigue cracking from an improperly machined radius of the inner tube, a drag stay broke, and, consequently, led to the collapse of the MLG during landing. We are proposing this AD to prevent such fatigue cracking, which could result in reduced structural integrity or collapse of the MLG.
Airworthiness Directives; Rolls-Royce Corporation (Formerly Allison Engine Company, Allison Gas Turbine Division, and Detroit Diesel Allison) 250-B and 250-C Series Turboprop and Turboshaft Engines
Document Number: 06-5547
Type: Rule
Date: 2006-06-21
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce Corporation 250-B and 250-C series turboprop and turboshaft engines with certain part numbers (P/Ns) of gas producer rotor assembly tie bolts manufactured by EXTEX Ltd., Pacific Sky Supply Inc., Rolls- Royce Corporation (RRC), and Superior Air Parts Inc. This AD requires operators to remove from service affected gas producer rotor assembly tie bolts, and install serviceable tie bolts. This AD results from eleven reports of RRC tie bolt failure due to high cycle fatigue. We are issuing this AD to prevent tie bolt failure that could cause loss of engine power, resulting in a first stage turbine wheel overspeed and an uncontained engine failure.
Airworthiness Directives; Pilatus Aircraft Ltd. Models PC-6, PC-6-H1, PC-6-H2, PC-6/350, PC-6/350-H1, PC-6/350-H2, PC-6/A, PC-6/A-H1, PC-6/A-H2, PC-6/B-H2, PC-6/B1-H2, PC-6/B2-H2, PC-6/B2-H4, PC-6/C-H2, and PC-6/C1-H2 Airplanes
Document Number: 06-5532
Type: Rule
Date: 2006-06-21
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) to revise AD 68-17-03, which applies to all Pilatus Aircraft Ltd. (Pilatus) PC-6 series airplanes. AD 68-17-03 requires you to repetitively inspect the rudder end rib for cracks and replace the rudder end rib with a modified rudder end rib when you find cracks. Installing the modified rudder end rib terminates the repetitive inspection requirements of AD 68-17-03. Under a licensing agreement with Pilatus, Fairchild Republic Company (also identified as Fairchild Industries, Fairchild Heli Porter, or Fairchild-Hiller Corporation) produced Model PC-6 series airplanes (manufacturer serial numbers 2001 through 2092) in the United States. AD 68-17-03 was intended to apply to all affected serial numbers of Model PC-6 series airplanes listed on Type Certificate Data Sheet (TCDS) No. 7A15, including the Fairchild-produced airplanes. Consequently, this AD clarifies that all models of the PC-6 airplane on TCDS No. 7A15 (including those models produced under the licensing agreement by Fairchild Republic Company) are included in the applicability. We are issuing this AD to detect and correct cracks in the rudder end rib, which could result in failure of the rudder end rib. This failure could result in loss of rudder control.
Airworthiness Directives; Airbus Model A300 B2 and A300 B4 Series Airplanes; and Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes)
Document Number: 06-5530
Type: Rule
Date: 2006-06-21
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Airbus airplanes as listed above. This AD requires repetitively inspecting for cracking in the web of nose rib 7 of the inner flap on the wings, and performing related investigative/corrective actions if necessary. This AD also requires eventual replacement of nose rib 7 with a new, improved rib, which would terminate the inspections. This AD results from reports of cracking in the web of nose rib 7 of the inner flap. We are issuing this AD to prevent cracking in the web of nose rib 7, which could result in rupture of the attachment fitting between the inner flap and flap track 2, and consequent reduced structural integrity of the flap.
Airworthiness Directives; Pacific Aerospace Corporation Ltd. 750XL Airplanes
Document Number: 06-5529
Type: Rule
Date: 2006-06-21
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) that supersedes AD 2005-26-53, which applies to certain Pacific Aerospace Corporation Ltd. (PAC) 750XL airplanes. AD 2005-26-53 currently requires you to insert text into the Limitations Section of the Airplane Flight Manual (AFM) that reduces the maximum takeoff weight from 7,500 pounds to 7,125 pounds. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for New Zealand and the FAA's decision that the actions correct an unsafe condition. Consequently, this AD would require you to remove rivets that have not been fully age hardened and replace them with bolts, washers, and nuts in specific locations where reduction in rivet strength affects overall structural capability. This AD retains the actions of the previous AD until the rivets are replaced with the bolts, washers, and nuts. We are issuing this AD so that wing ultimate load requirements are met. If wing ultimate load requirements are not met, wing failure could result with consequent loss of control of the airplane.
