C'mon, who hasn't had a gear 'hiccup' in the 1900?!
EAB-EAP are failry crappily built - EAQ, the ex US import, is alright - and it's been showing for donkeys. EAA - Air NZ's first - is still the best in the fleet!
When ya regularly throw the wheels into the breeze at 180kias at a simdge from the deck, spose ya gotta expect some get a bit 'worn'!!!
