Federal Aviation Administration May 13, 2019 – Federal Register Recent Federal Regulation Documents

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval to renew an information collection. The Information to be collected is necessary to insure the safety of the flying public. Documentation of maintenance repair actions record who, what, when, where and how of the task performed. All maintenance actions as well as documentation are required. This collection focuses on the Form 337 which is collected by the FAA. Other records for preventative maintenance, and logbook entries are not collected by the FAA serve as a responsibility of the owner to maintain in case of verification of airworthiness when seeking approvals or sale of the aircraft. This insures proper certification of personnel; proper tooling is utilized and accurate measures to insure safety. Total form 337s submitted in 2017 is 54,237. Total aircraft registrations on file is 289,490. It is estimated by the numbers collected one in every five aircraft have a 337 form submitted for major alteration and repairs performed. Each 337 takes approximately 1 hour.

The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD), which would have applied to all Airbus SAS Model A330-200 Freighter, A330-200, and A330-300 series airplanes. The NPRM would have required reinforcement modifications of various structural parts of the fuselage, and related investigative and corrective actions if necessary. Since the NPRM was issued, we have determined that more restrictive maintenance requirements are necessary and that the NPRM does not adequately address the identified unsafe condition. Accordingly, the NPRM is withdrawn.

We propose to adopt a new airworthiness directive (AD) for certain Learjet Inc. Model 60 airplanes. This proposed AD was prompted by a report of a reverse thrust command accelerating the airplane instead of decelerating the airplane. The acceleration with reverse thrust commanded occurred when the thrust reverser doors were in the stowed position instead of the deployed position. This proposed AD would require installing a Thrust Reverser (T/R) Voice Command Warning System (VCWS) to alert the crew of a T/R malfunction. We are proposing this AD to address the unsafe condition on these products.
