Airworthiness Directive · Amendment 39-21513 · Fire protection
The Boeing Company Airplanes
Superseded. A later AD replaced this one: AD 2023-08-02. Comply with the one in force.
This AD applies to all The Boeing Company Model 787-8, -9, and -10 airplanes, certificated in any category.
The FAA is superseding Airworthiness Directive (AD) 2021-02- 19, which applied to certain The Boeing Company Model 787-8, -9, and - 10 airplanes. AD 2021-02-19 required repetitive general visual inspections for disengaged or damaged decompression panels of the bilge barriers located in the forward and aft cargo compartments, reinstallation of disengaged but undamaged panels, and replacement of damaged panels. This AD was prompted by reports of multiple incidents of torn decompression panels found in the bilge area, and the determination that additional airplanes are subject to the unsafe condition. This AD retains the requirements of AD 2021-02-19 and revises the applicability by including additional airplanes. The FAA is issuing this AD to address the unsafe condition on these products.
At the applicable times specified in paragraph (g)(1) or (2) of this AD: Do a general visual inspection for disengaged or damaged (torn) decompression panels of the bilge barriers located in the forward and aft cargo compartments. If any disengaged but undamaged panel is found: Before further flight, reinstall the panel. If any damaged panel is found: Before further flight, replace the panel with a new or serviceable panel. Reinstallations and replacements must be done in accordance with the operator's maintenance or inspection program, as applicable.
(1) If a general visual inspection for disengaged or damaged (torn) decompression panels of the bilge barriers was done before the effective date of this AD: Do the next inspection within 4 calendar months after the most recent inspection. Repeat the inspection thereafter at intervals not to exceed 4 calendar months.
(2) If a general visual inspection for disengaged or damaged (torn) decompression panels of the bilge barriers was not done before the effective date of this AD: Do the initial inspection within 30 days after the effective date of this AD. Repeat the inspection thereafter at intervals not to exceed 4 calendar months.
If any decompression panel inspected as required by this AD is disengaged or damaged, the airplane may be operated as specified in the operator's existing FAA-approved minimum equipment list (MEL), provided provisions that address the disengaged or damaged decompression panels are included in the MEL.
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.
