Airworthiness Directive · Amendment 39-19550 · Fire protection
The Boeing Company Airplanes
Superseded. A later AD replaced this one: AD 2021-02-06. Comply with the one in force.
This AD applies to all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes, certificated in any category.
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD was prompted by reports of warpage of internal engine fire handle components, which can cause binding and prevent proper operation. We are issuing this AD to address the unsafe condition on these products.
Within 14 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to add airworthiness limitation 28-AWL-FIRE, by incorporating the information specified in figure 1 to paragraph (g) of this AD into the Airworthiness Limitations Section of the Instructions for Continued Airworthiness. The initial compliance time for accomplishing the actions specified in figure 1 to paragraph (g) of this AD is within 45 days after the effective date of this AD.
After accomplishment of the existing maintenance or inspection program revision required by paragraph (g) of this AD, no alternative actions (e.g., inspections) or intervals may be used unless the actions or intervals are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (j) of this AD.
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.
