Required actions
Within 165 hours time-in-service after the effective date of this AD, inspect the angle of the support bracket on the wing leading edge tank fuel pickup assembly and, before further flight, take any necessary additional actions and corrective actions by following the Accomplishment Instructions in Pacific Aerospace Mandatory Service Bulletin PACSB/XL/109, Issue 1, dated January 16, 2019.
Unsafe condition
This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as failure of the installation of the wing leading edge tank fuel pickup assembly in a pre-stressed condition, which could cause cracks in the wing spar web or the fuel pickup assembly pipe. The FAA is issuing this AD to prevent cracks in the wing spar web and the fuel pickup pipe. This condition could result in reduced structural integrity of the wing spar or cause a fuel leak, which could result in an engine fire.
Affected ADs
None.
