Irish-based AviaAM Leasing has transferred a second Boeing 777-300ER for cargo conversion by US-based Mammoth Freighters.
Mammoth is undertaking conversion of 777-200LR and -300ER twinjets.
AviaAM states that it ferried the -300ER to Fort Worth Alliance airport, where Mammoth partner Aspire MRO has a facility, on 28 February.
The leasing company entered an agreement for six conversions of passenger jets to -300ERMF freighters.
Its first aircraft, MSN35299, was inducted last year, Mammoth disclosed in October.
Mammoth had initially commenced conversion work on 777-200LRs but stated that the progress and momentum on these modifications had given it confidence to extend its programme to the -300ER.
Conversion of the twinjet involves floor-beam replacement and installation of a cargo door, among fitting of other features including a supernumerary area for personnel.
AviaAM says the aircraft will be able to transport just under 100t of freight and is likely to be operated on transatlantic or Europe-China routes.
