  • Simple preservation operations and replacing small standard parts (without complex assembly) is preventive maintenance.
  • Installing a non-approved engine accessory is a powerplant major modification/alteration.
  • Inspection of an aircraft away from its usual station can be done by a certified repair station or an appropriately licensed mechanic.
  • The licensed mechanic/owner is responsible for aircraft maintenance records being up to date.
  • Changes from a major repair alteration to an aircraft's operating limitations require CAAP-prescribed form and manner updates.
  • A 100-hour inspection requires noting the inspection date and aircraft time in service.

  • The recommended statement for aircraft approval/disapproval after a 100-hour or annual inspection is in 14 CFR Part 43.
  • Disassembling a crankcase or crankshaft of a reciprocating engine with an integral supercharger is powerplant major repair.
  • Repairs to spars, ribs, and surfaces involve the inspection and approval by the ATO.
  • Removing, installing, and repairing landing gear tires are typical preventive maintenance operations.
  • A component conforming to a technical standard order does not require an STC when used in alteration.
  • Repairing damaged areas exceeding 10 inches in stressed covering constitutes a major repair.
  • Modifications to the basic design not aligned with the appliance manufacturer's recommendations/airworthiness directives are appliance major modification.
  • Disassembly of a float-type carburetor is not considered a powerplant major alteration, but removing a piston is a powerplant major alteration.
  • Reconstructing lost/destroyed aircraft maintenance records requires establishing the airframe's total service.
  • Only the authority can disapprove an aircraft/component for return to service after maintenance/modification unless specified otherwise.
  • PCAR Part 6 is for MRO/AMO.
  • An appropriately licensed aircraft mechanic is only one of the people who can return to service a aircraft.
  • Airframe minor repair includes wing and control surface fairings.

  • Large airplanes and turbine-powered multi-engine airplanes are operated per federal aviation regulations, part 91, subpart E.
  • The registered operator must maintain permanent records of maintenance (excluding preventive maintenance), repairs of building or alterations.
  • A special flight permit can be issued to aircraft not meeting airworthiness requirements but capable of safe flight within limitations.
  • Changes to the basic design of a landing gear shock strut, as transport approved, are airframe major alteration.
  • An Approved Maintenance Organization (AMO) representative signs a document for an inspection, repair, or modification, which is a Maintenance Release.
  • Any repair to spars, ribs, and surface involves airframe minor repair techniques.
  • Overdue 100-hour inspections permit aircraft operation only to reach a place for inspection, based on continuous airworthiness program or hour meter equipment.
  • Restoring engine mounts to a good condition for safe operation after damage is a powerplant major repair.
  • Welding, plating, metalizing structural engine parts is an example of Powerplant major repair.
