Airworthiness Directive · Amendment 39-13878 · Ostmecklenburgische Flugzeugbau GmbH Model OMF-100-160 Airplanes
Ostmecklenburgische Flugzeugbau GmbH Model OMF-100-160 Airplanes
This AD affects Model OMF-100-160 airplanes, serial numbers 0006, 0007, 0012 through 0015, 0017, 0018, 0020, 0021, 0024, 0025, 0028, and 0029; that are certificated in any category.
The FAA adopts a new airworthiness directive (AD) for certain Ostmecklenburgische Flugzeugbau GmbH (OMF) Model OMF-100-160 airplanes. This AD requires you to inspect the outside tube (cage) that supports the main landing gear leg for cracks, repair if cracks are found, and inspect the thickness of the tube if no cracks were found and reinforce the tube as necessary. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to detect, correct, and prevent future cracks in the outside tube of the main landing gear leg, which could result in structural failure of the fuselage tubing assembly. This failure could lead to loss of control of the airplane.
To address this problem, you must do the following:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Inspect the main landing gear leg support for cracks | Inspect the airplane within 50 hours time-in-service (TIS) after December 28, 2004 (the effective date of this AD) | Inspect following the procedures in OMF Alert Service Bulletin No. 1107/0002, dated September 16, 2003. |
| (2) If cracks are found during any inspection required in paragraph (e)(1) or (e)(3)(ii) of this AD, obtain repair instructions from the manufacturer through the FAA and incorporate the repair instructions. This repair eliminates the repetitive inspection requirement of this AD | Repair prior to further flight after the inspection where cracks are found | Contact an Ostmecklengurgische Flugzeugbau GmbH (OMF) representative at 1-819-377-1177 for repair instructions and incorporate these instructions. Summarize and copy all correspondence and send to FAA at the address specified in paragraph (f) of this AD. |
| (3) If no cracks are found during the inspection required in paragraph (e)(1) of this AD, do the following: (i) inspect tubing for proper thickness and make any appropriate reinforcements (ii) repetitively inspect main landing gear leg support for cracks | Inspect for tubing thickness of the airplane within 50 hours TIS after the initial inspection required in paragraph (e)(1) of this AD. Reinforce prior to further flight after the inspection required in paragraph (e)(3)(i) of this AD. Repetitively inspect the main landing gear leg support within 50 hours TIS after the initial inspection required by paragraph (e)(1) of this AD and thereafter at intervals not to exceed 50 hours TIS | Inspect following procedures in OMF Alert Service Bulletin No. 1107/0002, dated September 16, 2003. Reinforce with instructions from the manufacturer. Contact an Ostmecklengurgische Flugzeugbau GmbH (OMF) representative at 1-819-377-1177 for repair instructions and incorporate these instructions. Summarize and copy all correspondence and send to FAA at the address specified in paragraph (f) of this AD. |
