Airworthiness Directive · Amendment 39-14115 · BAE Systems (Operations) Limited Model BAe 146 Airplanes
BAE Systems (Operations) Limited Model BAe 146 Airplanes
This AD applies to BAE Systems (Operations) Limited Model BAe 146-100A, -200A, and -300A series airplanes, certificated in any category; except those on which BAe Modification HCM00972A or HCM00972C has been accomplished.
The FAA is adopting a new airworthiness directive (AD) for certain BAE Systems (Operations) Limited Model BAe 146 airplanes. This AD requires repetitive inspections for cracks of the fuselage pressure skin above the left and right main landing gear (MLG) bay. This AD also requires corrective action, including related investigative actions, if leaks are found. This AD is prompted by reports of cracks in the fuselage pressure skin above the left and right MLG bay. We are issuing this AD to detect and correct fatigue cracking in the fuselage pressure skin above the left and right MLG bay; such fatigue cracking could adversely affect the structural integrity of the fuselage and its ability to maintain pressure differential.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
At the times specified in Table 1 of this AD, inspect the fuselage pressure skin above the left and right MLG bay for cracks in accordance with the Accomplishment Instructions of BAE Systems (Operations) Limited Inspection Service Bulletin 53-170, dated August 8, 2003.
| For airplanes listed in paragraph (c) of this AD— | Do initial inspections— | And do repetitive inspections thereafter— |
|---|---|---|
| On which neither BAe modification HCM00744M nor HCM00850A has been accomplished | Prior to the accumulation of 15,000 total flight cycles or within 500 flight cycles after the effective date of this AD, whichever occurs later | At intervals not to exceed 1,000 flight cycles. |
| On which either BAe modification HCM00744M or HCM00850A has been accomplished On which both BAe modifications HCM00744M and HCM00850A have been accomplished | Prior to the accumulation of 15,000 total flight cycles or within 1,000 flight cycles after the effective date of this AD, whichever occurs later | At intervals not to exceed 3,000 flight cycles. |
If any crack is found during any inspection required by paragraph (f) of this AD, do the corrective action and any related investigative actions, in accordance with the Accomplishment Instructions of BAE Systems (Operations) Limited Inspection Service Bulletin 53-170, dated August 8, 2003, except as required by paragraph (h) of this AD.
(h) If any cracking is found during any inspection or related investigative action required by this AD, and the service bulletin recommends contacting BAE Systems for appropriate action: Before further flight, repair the cracks according to a method approved by the Manager, International Branch, ANM-116, FAA, Transport Airplane Directorate; or the Civil Aviation Authority (or its delegated agent).
(i) Although the service bulletin referenced in this AD specifies to submit certain information to the manufacturer, this AD does not include that requirement.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
