AD 2021-16-15 Airworthiness Directives; The Boeing Company Airplanes
Models named: 737-8, 737-9, 737-8200, 737-800 series, 737-900ER series. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to The Boeing Company airplanes, certificated in any category, as identified in paragraphs (c)(1) through (3) of this AD. (1) All Model 737-8, 737-9, and 737-8200 airplanes. (2) Model 737-800 series airplanes, line numbers 5684 and 5759 and subsequent. (3) Model 737-900ER series airplanes, line numbers 5768 and subsequent.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Beginning August 19, 2021, no person may dispatch or release an airplane with cargo in the aft cargo compartment with failed electronic flow control of air conditioning packs, unless the aft cargo compartment remains empty, or is verified by the operator to contain only non-combustible and/or non-flammable empty cargo handling equipment, ballast, and/or fly-away kits. Note 1 to paragraph (g): The operator's existing FAA-approved minimum equipment list (MEL) defines which items are approved for inclusion in the fly-away kits, and which materials may be used as ballast.
Unsafe condition
This AD was prompted by the determination that the aft cargo fire suppression capability is reduced if the airplane is dispatched or released with failed electronic flow control of air conditioning packs. The FAA is issuing this AD to address this condition, which can result in an uncontained aft cargo compartment fire due to insufficient cargo fire suppression capability.
Affected ADs
None.
