This Special Airworthiness Information Bulletin is to alert owners, operators, and maintenance technicians of an issue that could affect crew visibility when utilizing full face masks/smoke goggles manufactured by Collins Aerospace (formerly Rockwell Collins, B/E Aerospace).
At this time, the airworthiness concern is not an unsafe condition that would warrant any additional airworthiness directive (AD) action under Title 14 of the Code of Federal Regulations (14 CFR) part 39.
We are adopting a new airworthiness directive (AD) for certain Aspen Avionics, Inc. (Aspen), Evolution Flight Display (EFD) EFD1000 Primary Flight Display (PFD), EFD1000 Multi- Function Display (MFD), EFD1000 Emergency Backup Display (EBD), and EFD500 MFD units installed on various aircraft. This AD requires disabling the Automatic Dependent Surveillance- Broadcast (ADS-B) In function and revising the Airplane Flight Manual Supplement (AFMS). This AD was prompted by reports of flight displays repetitively resetting. We are issuing this AD to address the unsafe condition on these products.
We are adopting a new airworthiness directive (AD) for certain Zodiac Aerotechnics (Zodiac) oxygen mask regulators. This AD was prompted by reports that certain silicon harness inflation hoses installed on certain flight crew quick donning mask harnesses have shown an unusually high premature rupture rate. This AD requires inspection and replacement of certain oxygen mask regulator harness inflation hoses. We are issuing this AD to address the unsafe condition on these products.
From the FAA: We propose to adopt a new airworthiness directive (AD) for certain Piper Aircraft, Inc. (Piper) Model PA-28-140, PA-28-150, PA-28-151, PA-28-160, PA-28-161, PA-28-180, PA-28-181, PA-28-235, PA-28R-180, PA-28R-200, PA-28R-201, PA-28R-201T, PA-28RT-201, PA-28RT-201T, PA-32-260, and PA-32-300 airplanes. This proposed AD was prompted by a report of a fatigue crack found in a visually inaccessible area of the lower main wing spar cap.
