A recent BBC Guernsey news item stated that Aurigny's Trislanders 'will last until 2034' - this can be viewed at:
BBC News - Aurigny's Trislanders 'will last until 2034'
The ATDB.aero site suggests that each Tri has acheived between 23 and 26 thousand hours to date - but does not record number of landings unfortunately.
This suggests they have found a way round the legislation mentioned in the posts below. It is also backed by a GEP article today suggesting that an ex Aurigny pilot still wants to buy the Tris and start a new Alderney based company.
Also a short session at the CAA web-site "G-INFO UK Register Database" indicated that the only aircraft leased by Aurigny is the ATR GBWDB. Incidently the same database shows that BI leases GDRFC from a Jersey based company (so might be an offshoot of BI?) and GJIBO from a North of England company (I think this is common knowledge). FlyBE seems to lease quite a lot of its aircraft (too many to check all).
Hope this helps the discussion - does anyone have any further info as to how the Tris can keep flying or who owns the planes?
