AD 2025-09507 Published 2025-05-28 1 model 390 US-registered tails affected Federal Register ↗

Abstract

The FAA is superseding Airworthiness Directive (AD) 2020-19- 13, which applied to certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. AD 2020-19-13 required a check to identify the manufacturer and part number of the portable oxygen bottle installation, and, if necessary, modification of the portable oxygen bottle installation. This AD continues to require the actions specified in AD 2020-19-13 and expands the applicability. This AD was prompted by a report indicating that the portable oxygen bottle installation's upper bracket latch assembly can catch on the pressure gauge tube or on the pressure gauge bezel of the portable oxygen bottle. This AD was also prompted by the determination that additional airplanes may be subject to the unsafe condition. The FAA is issuing this AD to address the unsafe condition on these products.

Applicability

Aircraft makes and models this AD applies to, sorted by US-registered fleet size.
