(d) SUBJECT
Air Transport Association (ATA) of America Code 33, Lights.
(e) REASON
This AD was prompted by a report of smoke and signs of an overheating
condition from the emergency light battery (ELB) due to excessive
corrosion surrounding the internal lead acid batteries, which caused
an electrical short circuit that led to the smoke and overheating
condition. The FAA is issuing this AD to address such conditions,
which could cause fire onboard the airplane.
(f) COMPLIANCE
Comply with this AD within the compliance times specified, unless
already done.
(g) INSPECTION AND CORRECTIVE ACTION
Within 15 months after the effective date of this AD, inspect the ELB
to determine the last replacement date or the manufacturing date, as
applicable; if during this inspection, any date is found to be 4 years
or older, replace the ELB before further flight. Do the actions in
accordance with the Accomplishment Instructions of Bombardier Service
Bulletin 700-33-024, dated May 13, 2019. For airplanes on which the
restoration task specified in paragraph (h) of this AD was done before
the effective date of this AD, the requirements of paragraph (g) of
this AD are not required.
(h) MAINTENANCE OR INSPECTION PROGRAM REVISION
Within 60 days after the effective date of this AD, revise the
existing maintenance or inspection program, as applicable, to include
the information specified in Bombardier BD-700 Supplemental Time
Limits/Maintenance Checks (STLMC) Chapter 5 task number 33-51- 54-603,
"Restoration of the Emergency Lighting Batteries (XL245-B Emergency
Battery System)," in the Bombardier BD-700 STLMC, as specified in the
applicable temporary revision identified in figure 1 to paragraph (h)
of this AD. The initial compliance time for doing task 33-51-54-603 is
at the applicable time specified in paragraph (h)(1) or (2) of this
AD. Repeat task 33-51-54-603 thereafter at the interval specified
within that task.
(1) If both ELBs were replaced at the time of compliance with paragraph
(g) of this AD: Within 48 months after the ELB replacement.
(2) If neither ELB, or only one ELB, was replaced at the time of
compliance with paragraph (g) of this AD: Within 48 months after the
applicable date specified in paragraph (h)(2)(i) or (ii) of this AD.
(i) For each ELB, use the battery replacement date, if it is indicated.
(ii) For each ELB, use the date of manufacture, if it does not have a
battery replacement date indicated.
