Federal Aviation Administration December 15, 2017 – Federal Register Recent Federal Regulation Documents

We propose to adopt a new airworthiness directive (AD) for Pacific Aerospace Limited Model 750XL airplanes. 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 incorrectly marked and annunciated low oil pressure indication warnings. We are issuing this proposed AD to require actions to address the unsafe condition on these products.

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 a generic information collection. As part of a Federal Government-wide effort to streamline the process to seek feedback from the public on service delivery, FAA has an approved Generic Information Collection Request (Generic ICR): ``Generic Clearance for the Collection of Qualitative Feedback on Agency Service Delivery''.

We propose to supersede Airworthiness Directive (AD) 2017-12- 03, which applies to certain Pratt & Whitney Division (PW) PW2037, PW2037M, and PW2040 turbofan engines. AD 2017-12-03 requires installing a software standard eligible for installation and precludes the use of electronic engine control (EEC) software standards earlier than SCN 5B/ I. Since we issued AD 2017-12-03, software became available for additional PW engines models. This proposed AD would require installing a software standard eligible for installation and preclude the use of EEC software standards earlier than SCN 5B/I or SCN 27A. We are proposing this AD to address the unsafe condition on these products.
