Columbia Aircraft Manufacturing (Previously the Lancair Company) Models LC40-550FG, LC41-550FG, and LC42-550FG Airplanes
Superseded. A later AD replaced this one: AD 2007-07-06 R1. Comply with the one in force.
This AD applies to the following airplane models and serial numbers that are certificated in any category:
| Model | Serial No. |
|---|---|
| LC40-550FG | 40001 through 40079. |
| LC41-550FG | 41001 and up. |
| LC42-550FG | 42001 and up. |
The FAA is adopting a new airworthiness directive (AD) for Columbia Aircraft Manufacturing (previously The Lancair Company) Models LC40-550FG, LC41-550FG, and LC42-550FG airplanes. This AD requires you to add information to the Limitations section of the Airplane Flight Manual (AFM). This AD also requires you to repetitively inspect the aileron and the elevator linear bearings and control rods for foreign object debris, scarring, or damage and take all necessary corrective actions. This AD results from reports of possible foreign object contamination of the linear bearings. We are issuing this AD to prevent jamming in the aileron and elevator control systems, which could result in failure. This failure could lead to loss of control.
To address this problem, you must do the following, unless already done:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Insert Appendix A of Columbia Mandatory Service Bulletin SB-07-002, dated March 14, 2007, into the Limitations section of the Airplane Flight Manual (AFM) | Before further flight after April 9, 2007 (the effective date of this AD) | The owner/operator holding at least a private pilot certificate as authorized by section 43.7 of the Federal Aviation Regulations (14 CFR 43.7) may do the AFM insertion requirement of this AD. Make an entry in the aircraft records showing compliance with this portion of the AD following section 43.9 of the Federal Aviation Regulations (14 CFR 43.9). |
| (2) Access and inspect the aileron and elevator linear bearings on both wings for foreign object debris | Initially inspect within the next 35 hours time-in-service (TIS) after April 9, 2007 (the effective date of this AD). Repetitively inspect thereafter at intervals not to exceed 12 calendar months | Following Columbia Mandatory Service Bulletin SB-07-002, dated March 14, 2007, and the applicable maintenance manual. |
| (3) Remove any debris found during any inspection required in paragraph (e)(2) of this AD | Remove any debris before further flight after the inspection in which the debris is found | Following Columbia Mandatory Service Bulletin SB-07-002, dated March 14, 2007, and the applicable maintenance manual. |
| (4) Inspect the aileron and elevator control rods for scarring or damage near the linear bearings | Initially inspect within the next 35 hours TIS after April 9, 2007 (the effective date of this AD). Repetitively inspect thereafter at intervals not to exceed 12 calendar months | Following Columbia Mandatory Service Bulletin SB-07-002, dated March 14, 2007, and the applicable maintenance manual. |
| (5) Contact the manufacturer at the address specified in paragraph (g)(2) of this AD for a repair scheme if any scarring or damage is found during any inspection required in paragraph (e)(4) of this AD | Make all repairs before further flight after the inspection in which scarring or damage is found | Following Columbia Mandatory Service Bulletin SB-07-002, dated March 14, 2007, and the applicable maintenance manual. |
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
