Airworthiness Directive · Amendment 39-21389 · Fire protection
The Boeing Company Airplanes
This AD applies to all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes, certificated in any category.
The FAA is superseding Airworthiness Directive (AD) 2019-02- 03, which applied to all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. AD 2019-02-03 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD retains the requirements of AD 2019-02-03 and requires incorporation of an airworthiness limitation that applies only to certain airplanes. This AD also requires replacing or modifying certain engine fire control panels, which terminates the revised airworthiness limitation added in this final rule when a certain condition is met. Since the FAA issued AD 2019-02-03, the manufacturer has developed a new fire handle design that will eliminate the need for the airworthiness limitations required by AD 2019-02-03. The FAA is issuing this AD to address the unsafe condition on these products.
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.
This paragraph restates the requirements of paragraph (h) of AD 2019-02-03, with a new exception. Except as required by paragraph (k) 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 (p) of this AD.
For the airplanes identified in Boeing Requirements Bulletin B787-81205-SB260008-00 RB, Issue 001, dated March 10, 2020: At the applicable times specified in the “Compliance” paragraph of Boeing Requirements Bulletin B787-81205-SB260008-00 RB, Issue 001, dated March 10, 2020, except as specified by paragraph (j) of this AD, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Requirements Bulletin B787-81205-SB260008-00 RB, Issue 001, dated March 10, 2020.
Note 1 to paragraph (i): Guidance for accomplishing the actions required by paragraph (i) of this AD can be found in Boeing Service Bulletin B787-81205-SB260008-00, Issue 001, dated March 10, 2020, which is referred to in Boeing Requirements Bulletin B787-81205-SB260008-00 RB, Issue 001, dated March 10, 2020.
Where Boeing Requirements Bulletin B787-81205-SB260008-00 RB, Issue 001, dated March 10, 2020, uses the phrase “the issue 001 date of Requirements Bulletin B787-81205-SB260008-00 RB,” this AD requires using “the effective date of this AD.”
Except as provided by paragraph (l) of this AD: Prior to or concurrently with the actions specified in paragraph (i) of this AD, or within 30 days after the effective date of the AD, whichever occurs later; revise the existing maintenance or inspection program, as applicable, by incorporating the information specified in figure 2 to paragraph (k) of this AD into the Airworthiness Limitations Section of the Instructions for Continued Airworthiness. It is acceptable to change the limitation number from 28-AWL-FIRE to 26-AWL-FIRE, provided the rest of the information in figure 2 to paragraph (k) of this AD remains unchanged. The initial compliance time for accomplishing the actions specified in figure 2 to paragraph (k) of this AD is within 30 days after accomplishing the last 28-AWL-FIRE or 26-AWL-FIRE task, as applicable. Accomplishing the revision required by this paragraph terminates the actions required by paragraph (g) of this AD.
For Model 787-8, -9, and -10 airplanes equipped with an engine fire control panel having part number 412600-001 or an engine fire shutoff switch having part number 417000-101 or 417000-102: As an alternative to performing the actions required by paragraph (k) of this AD, within 30 days after accomplishing the last 28-AWL-FIRE or 26-AWL-FIRE task or accomplishing the last operational check of the engine fire handle in accordance with Boeing Requirements Bulletin B787-81205-SB260007-00 RB, Issue 001, dated February 22, 2019; perform an operational check of the engine fire handle in accordance with Boeing Requirements Bulletin B787-81205-SB260007-00 RB, Issue 001, dated February 22, 2019. Repeat the operational check thereafter at intervals not to exceed 30 days. Accomplishing the initial check specified in this paragraph terminates the actions required by paragraph (g) of this AD.
Note 2 to paragraph (l): Guidance for accomplishing the actions specified in paragraph (l) of this AD can be found in Boeing Service Bulletin B787-81205-SB260007-00, Issue 001, dated February 22, 2019, which is referred to in Boeing Requirements Bulletin B787-81205-SB260007-00 RB, Issue 001, dated February 22, 2019.
After accomplishment of the existing maintenance or inspection program revision required by paragraph (k) of this AD, no alternative actions (e.g., inspections) or intervals may be used unless the actions or intervals are approved as an AMOC in accordance with the procedures specified in paragraph (p) of this AD.
Accomplishment of the actions required by paragraph (i) of this AD on all affected airplanes in an operator's fleet terminates the requirements of paragraph (k) of this AD.
