Federal Aviation Administration June 15, 2006 – Federal Register Recent Federal Regulation Documents

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: E6-9342
Type: Proposed Rule
Date: 2006-06-15
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 repetitive eddy current inspections to detect cracks of the outer skin of the fuselage at certain frames, and repair or reinforcement of the structure at the frames, if necessary. The existing AD also requires eventual reinforcement of the structure at certain frames, which, when accomplished, terminates the repetitive inspections. This proposed AD would add, for airplanes that were previously reinforced but not repaired in accordance with the existing AD, a one-time inspection for cracking of the fuselage outer skin at frames 28A and 30A above stringer 30, and repair if necessary. This proposed AD results from a report that the previously required actions were not sufficient to correct cracking before the structural reinforcement was installed. We are proposing this AD to prevent such fatigue cracking, which could result in reduced structural integrity, and consequent rapid decompression of the airplane.
Special Conditions: Societe de Motorisation Aeronautiques (SMA) Engines, Cessna Models 182Q and 182R: Installation of Model SR305-230 Aircraft Diesel Engine for Full Authority Digital Engine Control (FADEC) System and the Protection of the System From the Effects of High Intensity Radiated Fields (HIRF)

This proposes special conditions for the Cessna Models 182Q and 182R airplanes with a Societe de Motorisation Aeronautiques (SMA) Model SR305-230 aircraft diesel engine (ADE). The supplemental type certificate for these airplanes will have a novel or unusual design feature associated with the installation of an aircraft diesel engine that uses an electronic engine control system instead of a mechanical control system. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. 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 airworthiness standards.
