Models named: 737-600, -700, -700C, -800, -900, -900ER series. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes, certificated in any category, as identified in Boeing Special Attention Service Bulletin 737-54-1046, dated February 16, 2011.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Within 60 months after the effective date of this AD, replace the thumbnail fairing edge seals, on both the left side and the right side of engine 1 and engine 2, with new Nitronic 60 stainless steel alloy seals, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 737-54-1046, dated February 16, 2011.
Unsafe condition
This AD was prompted by reports of excessive in-service wear damage of the thumbnail fairing edge seal, and of the panel rub strip and skin assembly of the fan cowl. We are issuing this AD to prevent failure of the fire seal, which could allow a fire in the fan compartment to spread beyond the firewall and reach the flammable fluid leakage zones, resulting in an uncontrolled fire.
Affected ADs
None.
