Airworthiness Directive · Amendment 39-19220 · Fire protection
Airbus Airplanes
This AD applies to Airbus Model A320-214, -251N, and -271N airplanes, certificated in any category, having manufacturer serial numbers 07126, 07141, 07189, 07200, 07221, 07226, 07235, 07245, 07251, 07256, 07264, 07272, 07279, 07319, 07337 and 07340.
We are adopting a new airworthiness directive (AD) for certain Airbus Model A320-214, -251N, and -271N airplanes. This AD requires an inspection for any damaged bolt and nut in each cargo fire extinguishing bottle installation, and replacement of any damaged bolt and nut. This AD was prompted by a report that a dynamometric key, previously used for installing the cargo fire extinguishing bottle system, was out of tolerance. As a result, an incorrect torque value may have been applied to the bolts maintaining the fire extinguishing bottles in place. We are issuing this AD to address the unsafe condition on these products.
Within 30 days after the effective date of this AD: Do a general visual inspection for any damaged bolt and nut in each cargo fire extinguishing bottle installation in accordance with the instructions in Airbus Alert Operators Transmission A26N003-16, Revision 01, dated June 12, 2017.
(1) If any damaged bolt or nut is detected, before further flight, replace all damaged bolts and nuts, in accordance with the instructions in Airbus Alert Operators Transmission A26N003-16, Revision 01, dated June 12, 2017.
(2) If no damage is detected, before further flight, reinstall the bolts and nuts, in accordance with the instructions in Airbus Alert Operators Transmission A26N003-16, Revision 01, dated June 12, 2017.
Note 1 to paragraph (g) of this AD: No credit will be provided for accomplishment of the actions in the original issue of Airbus Alert Operators Transmission A26N003-16 because the torque values were incorrect.
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.
