Agency Information Collection Activities: Requests for Comments; Clearance of Renewed Approval of Information Collection: FAA Safety Briefing Readership Survey
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 survey will help the editors learn more about the target audience and how they elect to improve their safety skills/ practices, and what they need to know to improve their safety skills/ practices. With this information, the editors can craft FAA Safety Briefing content targeted to its audience to help accomplish the FAA and Department of Transportation's mission of improving safety.
Airworthiness Directives; Honeywell International Inc. Turboprop Engines
We propose to adopt a new airworthiness directive (AD) for certain Honeywell International Inc. TPE331-5, -5A, -5AB, -5B, -10, - 10R, -10U, -10UF, -10UG, -10UGR, and -10UR model turboprop engines. This proposed AD was prompted by engine propeller shaft coupling failures, leading to unexpected propeller pitch changes resulting in high aerodynamic and asymmetric drag on the airplanes using these engines. This proposed AD would require removing certain part number (P/N) propeller shaft couplings from service. This proposed AD would also require inserting a copy of Honeywell International Inc. Operating Information Letter OI331-26, dated March 2, 2010, into the applicable Airplane Flight Manuals. We are proposing this AD to prevent loss of airplane control, leading to an accident.
Airworthiness Directives; Turbomeca S.A. Turboshaft Engines
We propose to adopt a new airworthiness directive (AD) for certain Turbomeca S.A. Makila 2A and Makila 2A1 turboshaft engines. This proposed AD was prompted by failure of two high-pressure (HP) fuel pumps that resulted in engine in-flight shutdowns. This proposed AD would require initial and repetitive visual inspections, and replacement of the splines of the HP fuel pump/metering valve and the module M01 drive gear, if necessary. We are proposing this AD to prevent failure of the HP fuel pump, which could lead to an in-flight shutdown, damage to the engine, and forced landing or accident.
Airworthiness Directives; Pratt & Whitney Canada Corp. Turboprop Engines
We are revising an earlier proposed airworthiness directive (AD) for all Pratt & Whitney Canada Corp. (P&WC) PT6A-114 and PT6A-114A turboprop engines. The NPRM proposed to require initial and repetitive borescope inspections (BSIs) of compressor turbine (CT) blades, and the removal from service of blades that fail inspection. The NPRM was prompted by several incidents of CT blade failure, causing power loss and in-flight shutdown of the engine resulting in four fatalities. This action revises the NPRM by adding a mandatory terminating action. We are proposing this supplemental NPRM (SNPRM) to prevent failure of CT blades, which could lead to damage to the engine and damage to the airplane. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on this proposed change.
