Models named: 787-8, 787-9, 787-10. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes, certificated in any category.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

This paragraph restates the requirements of paragraph (g) of AD 2019-02-03, with no changes. Within 14 days after February 22, 2019 (the effective date of AD 2019-02-03), 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 February 22, 2019. BILLING CODE 4910-13-P ER23FE21.013

Unsafe condition

This AD was prompted by reports of warpage of internal engine fire handle components that can cause binding and prevent proper operation, and by the development of a new fire handle design that will prevent the unsafe condition. The FAA is issuing this AD to address a latent failure of the engine fire handle, which could result in the inability to extinguish an engine fire that, if uncontrollable, could lead to wing failure.

Affected ADs

This AD replaces AD 2019-02-03, Amendment 39-19550 (84 FR 2437, February 7, 2019) (AD 2019-02-03).
