1Hot-Day Roughness on a Fuel-Injected Trainer: Vapor Lock or Nozzle Fault?
A flight school's fuel-injected, four-cylinder horizontally opposed engine (angle-valve, 200 hp) shuts down for a 50-minute lunch stop at a sea-level airport on a 36 °C afternoon. The pilot reports a normal start but roughness during the run-up at 1800 RPM: the fuel-flow gauge fluctuates between 7 and 11 gph, and EGTs on cylinders 3 and 4 sit about 80 °F higher than 1 and 2.

An AME at a small approved maintenance organisation is asked to inspect a retractable-gear single used by a flying club that also gives ab initio instruction for hire. The records show: the last annual/periodic inspection signed 11 months and 15 days ago; 87 hours flown since, 62 of them on instructional flights for hire; a recurring airworthiness directive on the engine oil cooler requiring inspection every 100 hours' time in service, last recorded at 1,240.6 hours total time, with no later entry, while the tachometer now reads 1,352.4; and a propeller overhaul called for by the manufacturer at 2,000 hours or six years, last performed six years and four months ago.
