• Upon arrival at our facility, an initial inspection is conducted to assess its current condition and identify any major unforeseen issues.
  • Photos are taken throughout the process to allow our customers visual documentation.
  • Engines are carefully torn down, cleaned, and sent through an inspection process.
  • Components slated for reuse are visually inspected, NDT inspected, and measured to verify the items are within tolerances and meet “factory new” specifications. Our engines meet or exceed factory new specifications and tolerances, so they perform as well as or better than a factory new engine. Only airworthy parts are reused.
  • Engines are reassembled to exact standards and new components (OEM or PMA parts) are purchased from top-tier suppliers. Pinnacle Aircraft Engines uses a “one person–one engine “assembly process, unlike the first time the engine was assembled by the factory. Each assembler takes an engine from its individual components all the way to final assembly and comprehensive testing, so it can be certified as “airworthy”. Every engine is assembled according to the manufacturer’s approved Overhaul Manual.
  • The assembler’s work is inspected by the Chief Inspector throughout the build process, following detailed checklists. Only then does the engine move to the testing phase.
  • Finally, to ensure the engine will perform better than new and meet our high expectation of excellence, we test it thoroughly (on our calibrated State-of-the-Art Dynamometer). Our testing helps to ensure correct piston ring seating, measure/record engine torque, and horsepower output. Using an elaborate computer-linked data acquisition system, each engine receives an average hour and a half to two-hour test run. During this test, we monitor RPM, temperatures, pressures, and flows so we can confirm the performance and conformance to Factory standards.
