You must provide your airplane data (Make/Model/SerialNumber for airframe, engine, propeller, magnetos, carburetor and accessories) at least one week before the scheduled inspection. We will conduct the search for Airworthiness Directives (ADs). Your logbooks are the first thing we look at on the day of the inspection. We provide a clean workspace (hangar) unless its nice outside. You must have your basic set of aircraft mechanic hand tools available.Dont worry we have tools too. We will have all required special tools for the inspection. We will provide you with the inspection checklist in advance, and you will have the aircraft opened up and “pre-inspected” after you arrive for the formal inspection process. Bring your normal consumable parts you have already purchased and ready to go (oil, filters, spark plug washers, gaskets, o-rings, brake lining, cotter pins, grease, lubricants, tie wraps, safety wire, etc).If not we can help you order the parts necessary .The following category lists represent the minimum required amount of preparation that you need to have done before we start the inspection.

If you wish to document the time spent performing this annual maintenance on your aircraft, and receive credit toward the practical experience requirements to earn your Mechanic Certificate, we will be happy to verify it with a logbook entry. Annual inspection or condition inspection time qualifies, as does time spent performing preventative maintenance (as allowed by Part 43.3 and Appendix A). In addition, there are many “mechanic only” repairs that you can perform under supervision of an IA that will also count. Call us at 509-765-9519 to discuss this.
