Hmm. Logbook entry for a non-flight, which certainly did provide a learning point to remember....
With Warwick Brady, as my instructor, in a Wycombe Air Centre 152, long long ago - I think it was 1984.... Had a bit of trouble trying to start the engine, so Warwick gave it a few positive pumps on the prime, and the engine caught on fire! He grabbed the extinguisher, jumped out and began to squirt, I shut down and made a sharp exit....Warwick said go tell them in the office, quick! So I moved calmly - keep calm! don't panic! into the building and remarked "We seem to have an engine fire...." Well, it was like stirring up a nest of ants, everyone began rushing about in all directions. The Cessna sat there, sulking, fire extinguished, still puffing a wisp of smoke. The Chief Engineer took the situation in hand, we decided to fly in something else.
In the Red Baron at lunchtime, Dave Rich said "Don't worry about it, Mary, it was only a Cessna, there's plenty more where that came from!"
Learning point, don't overprime a balky engine.
