AD 2004-06-09 Airworthiness Directives; The Lancair Company Models LC40-550FG and LC42-550FG Airplanes
Applicability*9
(c) This AD affects the following airplane models and serial numbers that are certificated in any category: Model Serial numbers LC40-550FG 40004 through 40079 LC42-550FG 42002 through 42045
Required actions
(e) To address this problem, you must do the following: Actions Compliance Procedures (1) Inspect the fuel pressure transducer, as follows: (i) Visually inspect the fuel inlet of the transducer for chafing (surface discontinuity or discoloration) (ii) If chafing is found, use a caliper and measure the outside diameter of the fuel inlet fitting (rotating the transducer while noting the minimum cross sectional measurement). If the measurement is 0.370 inches or more and there is no evidence of fuel leakage, then repetitively inspect until you do the modification in paragraph (e)(3) of this AD Initially, unless already done within the last 25 hours time-in-service (TIS), inspect upon accumulating 100 hours TIS or within 5 hours TIS after May 3, 2004 (the effective date of this AD), whichever occurs later Repetitively inspect thereafter at intervals not to exceed 25 hours TIS until the modification in paragraph (e)(3) of this AD is done. The modification in paragraph (e)(3) of this AD is terminating action for the repetitive inspection requirements in this AD Follow The Lancair Company Model 300/350 Mandatory Service Bulletin No. SB-04-002B, dated March 10, 2004, and the applicable airplane maintenance manual. (2) If the measurement of the outside diameter of the fuel inlet fitting is 0.369 inches or less, do the modification in paragraph (3)(3) of this AD Before further flight after the inspection required in paragraph (e)(1) of this AD in which the measurement of 0.369 inches or less is found Follow The Lancair Company Model 300/350 Mandatory Service Bulletin No. SB-04-002B, dated March 5, 2004, The Lancair Company Model 300/350 Compliance Kit Instruction No. CK-002, dated March 10, 2004, and the applicable airplane maintenance manual. (3) Install Compliance Kit CK-002 Within 100 hours TIS after May 3, 2004 (the effective date of this AD) or before further flight if the criteria in paragraph (e)(2) of this AD exists. You may do this installation before this time as terminating action for the repetitive inspection requirements Follow The Lancair Company Model 300/350 Compliance Kit Instruction No. CK-002, dated March 10, 2004, and the applicable airplane maintenance manual.
Unsafe condition
(d) This AD is the result of several reports of that the fuel pressure transducer had worn through at the threads where it attached to the fuel line. We are issuing this AD to detect and correct chafing and wear of the fuel pressure transducer, which could result in failure of the transducer threaded fitting with a resulting fuel leak. These fuel leaks could lead to engine power loss or fire.
