But Piper are (still) quoting the same figure- 180m LDR on a hard surface, as the sportcruiser POH referenced by the AAIB report.
I can't imagine that LAA would have failed to point out to AAIB before publication if their performance figures corresponded to a different aeroplane - instead they are quoted as saying they will review and possibly insist on re-issue of the manuals.
Plus I can't offhand think of any reason why an aeroplane with a fixed pitch prop would take 180m to land, when the same aeroplane with a VP prop would take 327m.
