ATSB Report on Chipmunk Spinning Accident
A well written and most interesting report on a Chipmunk spinning accident that occurred at Coffs Harbour in 2014. CFI's and aircraft owners should be particularly interested because of the need to always ensure aircraft flight manual documentation is valid and up to date.
Investigation: AO-2014-114 - Collision with terrain involving DHC-1, 'Chipmunk' VH-UPD near Coffs Harbour, NSW on 29 June 2014
On another subject of Chipmunk operations and that is check items. The ATSB report discusses the various Chipmunk flight manuals and includes the original version of the `standard` POH. The Royal Air Force "Pilot's Notes for Chipmunk T10" was first published in February 1950 and reflected the then RAF Central Flying School policy of keeping non-essential items out of checks . For example, the published Final Checks for Landing in the afore-mentioned publication, state just four items for the pilot to remember. They are:
Fuel ...... Contents
Mixture....Fully Rich
Brakes.....Lever off.
Flaps.......As Required.
The Cessna 172N (1980) Information manual has a similar number of Before Landing checks:
Seats, Belts, Harnesses....Secure.
Fuel selector Valve...........Both.
Mixture.......................... Rich.
Carburettor Heat..............On (apply full heat before reducing power).
Now contrast the above Before Landing checks with that commonly taught in most of todays flying schools as generic (i.e.non type specific)
Brakes.
Undercarriage.
Mixtures.
Masters.
Mags.
Harness and Hatches.
Fuel.
Temps and Pressures.
Carb Heat.
Pitch Control.
Flaps.
Note the difference between the Manufacturer's published checks and that of the significant number of superfluous checks encouraged by most flying schools... Draw your own conclusions as to the easiest for students to remember and yet still cover the Manufacturer's flight safety intent.
