Airworthiness Directive · Amendment 39-16883 · Doors
BAE Systems (Operations) Limited Airplanes
This AD applies to all BAE Systems (Operations) Limited Model 4101 airplanes, certificated in any category.
We are adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model 4101 airplanes. This 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:
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 6 months after the effective date of this AD, do an ultrasonic inspection of the passenger/crew door upper and lower guide plates for a split caused by exfoliation corrosion, in accordance with the Accomplishment Instructions of BAE SYSTEMS (Operations) Limited Service Bulletin J41-52-064, dated September 15, 2009. Repeat the ultrasonic inspection, thereafter, at intervals not to exceed 48 months.
(h) If a split caused by exfoliation corrosion of an area of 78mm 2 (0.12 in. 2) or greater is found during any ultrasonic inspection required by paragraph (g) of this AD: Before further flight, replace any affected guide plates with a serviceable guide plate, in accordance with the Accomplishment Instructions of BAE Systems (Operations) Limited Service Bulletin J41-52-064, dated September 15, 2009.
Note 1: This AD differs from the MCAI and/or service information as follows: No differences.
