Typical Air Plains 180 FACTORY INSTALLATION
(Air Plains Work Order for installing your APS 180)

  1. Perform Air Plains "Pre-disassembly" inspection. in accordance with APS Checklist.
    Step 1 of our conversion involves a quick, initial test flight. It allows us the opportunity to record the performance of the old engine and any notable discrepancies. These items are, of course, discussed with the owner prior to the start of any work. We also inventory and check over your aircraft prior to starting any work.... to ensure a timely delivery upon completion.
  2. Install AIR PLAINS 180 horse engine in accordance with APS STC No. 5A4428SW.
    Step two involves the actual commencement of engine conversion, and becomes more detailed in the following steps.
  3. Perform Air Plains disassembly inspection.
    As your engine comes apart and off of the aircraft, we begin our inspection of your engine baffles, carb heat induction airbox, exhaust stacks, cowl shock mounts, fasteners, and all related removed components. ANY DISCREPANCIES FOUND on your baffles, airbox, and exhaust stacks, etc. (Re-used from your airframe) will be discussed for needed repair. We prefer to improve these components to "like new" condition, prior to modifying them to fit the new engine.
  4. Install AIR PLAINS 2500-2550 Gross Weight Increase Kit.
    Normally 2-3 hours, this step involves the limitation of flap travel to thirty degrees, and the installation of a new airspeed indicator ON 172K-P MODELS ONLY.
  5. Inspect aircraft for 6 ply tires.
    6 ply tires are required as a part of the 2500-2550 Gross Weight Increase AVAILABLE ON 1969 AND NEWER AIRPLANES. If you need a tire or two, we will let you know,
  6. Perform static system leak test BEFORE and AFTER installing new airspeed indicator. Record leak rates, report any leak rates in excess of 100 feet per minute in accordance with FAR 91.411 paragraph A(2).
    During the installation of your new air-speed indicator, your static system will be leak checked in accordance with the FAR's. Any leak rates in excess of the required limits will he repaired with your permission.
  7. Perform flight test of new engine in accordance with APS checklist and Lycoming recommended break in procedures.
    This involves several steps and inspections, and in the end, your aircraft engine will be test flown for approximately 3-4 hours, inspected several times, and then re-inspected once more for final delivery. NOTE: APS personnel will take special time to instruct you on the performance and break in procedures for your new Lycoming engine, before delivery.
  8. Weigh aircraft with electronic scales upon completion of all maintenance and modifications.
    Chances are that this will be the first time your aircraft has been weighed since it came from the factory. Our scales are re-calibrated on a regular-basis, to guarantee exact weight, balance, and C.G. computations.

  12. SHEET METAL REPAIRS:
    Advise of any repairs needed to refurbish engine baffles airbox exhaust stacks etc to "like new" condition. Please itemize for customer notification and approval.
    Required or excessive repairs are completed on a quote and bid basis. Our sheet metal personnel can usually refurbish an entire set of baffles to new condition for less than the cost of buying one new baffle from the Cessna factory. NOTE: the engine components listed should not need any repair work, due to the fact that you are flying under a current annual inspection.
    After refurbishment, the sheet metal components to be installed on the engine are completely cleaned, treated, primed, painted, and reinstalled with new 1/8th inch thick red silicone baffle seal.
