1. Database Update Debate The Federal Aviation Administration (FAA) proposal allowing Part 135 pilots to update databases of certain navigation equipment without the aid of certified mechanics or repair stations has raised the hackles of parties who feel they were either unfairly excluded from or potentially included in this new thinking. The notice of proposed rulemaking (NPRM), published Oct. 19, 2011, allows Part 135 pilots who operate aircraft with self-contained, front-panel or pedestal- mounted navigation equipment,” where no disassembly is required, to update these systems. UPS objected to the FAA’s assumption that Part 121 carriers would be unaffected by the proposal, as their nav systems don’t conform to the agency’s requirements. The package hauler wants air transport pilots to be included, provided that the update task requires no special tools and “can be accomplished by elementary operations.” Delta Air Lines makes a similar argument. The Air Line Pilots Association, however, rejects the proposal as unsafe, oppressive and potentially disruptive of labor harmony. Even the Aircraft Owners and Pilots Association (AOPA) is less than elated with FAA’s handiwork although private pilots already enjoy updating discretion. AOPA wants to eliminate the requirement for a maintenance record entry, which it deems redundant, and to include electronic chart, terrain and obstacle databases of similar configuration to the systems covered in the proposal.
2. 737 AD Expansion
The Federal Aviation Administration (FAA) in January 2012 adopted an airworthiness directive (AD) for the U.S. 737 fleet, requiring repetitive inspections, lubrications, and repetitive overhauls of the ball nut and ballscrew and attachment fittings for the trim actuator of the horizontal stabilizer, various modification(s) and corrective actions if necessary. The move aims, in FAA’s words, to prevent an undetected failure of the primary load path for the ballscrew in the drive mechanism of the horizontal stabilizer trim actuator and subsequent wear and failure of the secondary load path, which could lead to loss of control of the horizontal stabilizer and consequent loss of control of the airplane. The new AD, which expands the applicability of the original proposal, becomes effective Feb. 10, 2012, and covers 1,641 airplanes.
3. 777 Thrust Reverser AD
The Federal Aviation Administration (FAA) also aims to adopt another airworthiness directive (AD) to address potential thermal damage to thrust reversers (T/Rs) on the Rolls-Royce RB211 Trent 800 engines of certain 777-200 and -300 series airplanes. The proposed AD would involve replacement of bleed valve parts and tubing on the left and right engines as well as installation of Aero-Engine database software. The measure seeks to avert the possibility of rejected takeoffs and loss of control from T/R failures in which large pieces of the T/R or adjacent components are dislodged from the aircraft. The agency requested comments by Jan. 26, 2012.
