B/E Aerospace Protective Breathing Equipment Part Number 119003-11 and Part Number 119003-21
This AD applies to B/E Aerospace Protective Breathing Equipment (PBE), part numbers (P/N) 119003-11 and 119003-21, that are installed on airplanes.
We are superseding Airworthiness Directive (AD) 2016-11-20 for certain B/E Aerospace protective breathing equipment (PBE) that is installed on airplanes. AD 2016-11-20 required replacing part number (P/N) 119003-11 PBE units. Since we issued AD 2016-11-20, we received a report that PBE units, P/N 119003-21, within a certain serial number range are made with candle tube material determined to have a low yield strength and may be volatile upon use or disposal. This AD retains the actions required in AD 2016-11-20 and requires inspecting and replacing P/N 119003-11 and 119003-21 PBE units. We are issuing this AD to address the unsafe condition on these products.
Within 3 months after July 15, 2016 (the effective date of AD 2016-11-20), while still in the stowage box, physically inspect the PBE pouch to determine if it has an intact vacuum seal. Do this inspection following paragraph III.A.(1) of the Accomplishment Instructions in B/E Aerospace Service Bulletin (SB) No. 119003-35-011, Rev. 000, dated February 4, 2015.
(1) During the inspection required in paragraph (g) of this AD, if a PBE pouch is found that does not have an intact vacuum seal, before further flight, replace the PBE with a PBE unit, P/N 119003-21 that is not within the serial number (S/N) range 004-14768M through 004-21093M or 004-02393M through 004-03033M, following paragraphs III.C., III.D.(4), III.D.(6), and III.D.(7) of the Accomplishment Instructions in B/E Aerospace SB No. 119003-35-009, Rev. 001, dated April 12, 2016, or replace it with another FAA-approved PBE installation.
(2) During the inspection required in paragraph (g) of this AD, if a PBE pouch is found where the vacuum seal is intact, within 18 months after July 15, 2016 (the effective date of AD 2016-11-20), remove PBE, P/N 119003-11, and replace it with a PBE, P/N 119003-21 that is not within the S/N range 004-14768M through 004-21093M or 004-02393M through 004-03033M, following paragraphs III.C., III.D.(4), III.D.(6), and III.D.(7) of the Accomplishment Instructions in B/E Aerospace SB No. 119003-35-009, Rev. 001, dated April 12, 2016, or replace it with another FAA-approved PBE installation.
(3) Once a discrepant PBE has been identified during an inspection or review of records, the unit must be removed before further flight. However, continued operation with fewer than required PBE is permissible if allowed by your MEL.
Within 6 months after October 16, 2017 (the effective date of this AD), inspect to determine if the S/N of the installed PBE, P/N 119003-21, is within the range of 004-14768M through 004-21093M or 004-02393M through 004-03033M. Do the inspection following paragraph III.A of the Accomplishment Instructions in B/E Aerospace SB No. 119003-35-013, Rev. 002, dated July 19, 2017.
(1) Instead of the inspection, you may do a maintenance records review, to determine the S/N of the installed PBE, P/N 119003-21.
(2) If you choose to do the maintenance records review and you can positively determine that the S/N of the installed PBE, P/N 119003-21, is within the range of 004-14768M through 004-21093M or 004-02393M through 004-03033M, continue to the replacement requirement in paragraph (j) of this AD.
(3) If you choose to do the maintenance records review and you cannot positively determine that the S/N of the installed PBE, P/N 119003-21, is within the range of 004-14768M through 004-21093M or 004-02393M through 004-03033M, then you must either go back and do the inspection specified in paragraph (i) of this AD to determine if the replacement in paragraph (j) of this AD is necessary or do the replacement in paragraph (j) of this AD.
During the inspection or the maintenance records review required in paragraph (i) of this AD, if it is found that the PBE, P/N 119003-21, is within the S/N range specified in paragraph (i) of this AD, before further flight, remove the PBE and replace it with a PBE, P/N 119003-21, that does not have a S/N 004-14768M through 004-21093M or 004-02393M through 004-03033M. Do this replacement following paragraphs III.C., III.D.(4), III.D.(6), and III.D.(7) of the Accomplishment Instructions in B/E Aerospace SB No. 119003-35-013, Rev. 002, dated July 19, 2017, or replace it with another FAA-approved PBE installation. Once a discrepant PBE has been identified during an inspection or review of records, the unit must be removed before further flight. However, continued operation with fewer than required PBE is permissible if allowed by your MEL.
As of October 16, 2017 (the effective date of this AD), do not install a PBE, P/N 119003-21, that has a S/N within the range of 004-14768M through 004-21093M or 004-02393M through 004-03033M.
If you performed the inspection and replacement action required in paragraphs (i) and (j) of this AD before October 16, 2017 (the effective date of this AD) using B/E Aerospace SB No. 119003-35-013, Rev. 000, dated January 9, 2017, or B/E Aerospace SB No. 119003-35-013, Rev. 001, dated February 24, 2017, you have met the requirements of those paragraphs of this AD.
