A standard postflight procedure for a general aviation training aircraft typically includes

Choices

• no postflight actions, as the next preflight inspection covers all operational needs.

  Incorrect. No regulation requires a postflight inspection, but skipping it leaves new damage, leaks and squawks undiscovered for the next pilot.

• ✓ recording Hobbs and tach times, checking the aircraft for leaks or unrecorded damage, and securing the controls and tie-downs.correct

  No part of 14 CFR 91 requires a postflight inspection of a small piston airplane — 91.7 addresses airworthiness and 91.103 preflight action. The AFH (Ch. 2) presents postflight as recommended practice: record Hobbs and tach time, walk around for leaks or new damage, install the control lock or secure the yoke with the seatbelt, chock or tie down, fit pitot and window covers, and write up any squawks. Fuel sumping is a PREFLIGHT item, performed after water has had time to settle.

• a full 100-hour mechanical inspection.

  Incorrect. A 100-hour inspection is scheduled maintenance performed by certificated maintenance personnel, not a postflight action.

• draining all fuel tanks and sumps for overnight parking.

  Incorrect. Fuel sumping belongs to the PREFLIGHT, where water and sediment that settled overnight can be found and drained before flight. Draining tanks for parking invites condensation.
