So long as the hull and the wings aren't bent, it can be repaired if the insurer sells it cheap enough (say under £10k).
The report is interesting for its scandalous disclosures of previously little-known gems like this
As with many light aircraft of an older design, the fuel gauges appeared to be of little benefit to the pilot in accurately monitoring the amount of fuel onboard
Fuel consumption can also be affected by:
‘the equipment installed, the condition of engines, airplane and equipment, atmospheric conditions and piloting technique’
I always thought that this kind of knowledge ranked with masonic secrets, where the Nazi gold is stored, whether the US has UFO wreckage and alien bodies, and whether the NSA has found a way to rapidly factorise products of large primes
I would replace "many" with "practically all".
I can finally appreciate why the AAIB job adverts say you need to have an ATPL, which they will keep current for you.
It does amaze me (well actually it doesn't) that people are still doing "serious" flights like this, without a fuel totaliser linked to a GPS. The totaliser costs about £2k to install, less on an N-reg, and the IFR GPS you probably already have. Then you get a constantly recomputed "Landing FOB"
figure. Then you know what you've got instead of relying on data in a decades-old POH.
