Pays Air Service - Engineering


Pay’s Air Service has a fully licenced maintenance, repair and overhaul facility at our Scone base. Employing around 20 staff with part 66 licence coverage of B1.1, B1.2, B1.3 and B1.4. This allows us to maintain piston engine aircraft including retractable, turbocharged/supercharged, hydraulics, air conditioning/pressurisation and fabric/dope.

We also maintain and have extensive experience in aircraft equipped with PT6 series and Allison 250 B series turbine engines, and we are an approved overhaul facility for Rolls Royce/Packard Merlin and Griffin series, Allison V1710 series and Gypsy Major series.

Over the years Pay’s have engineered many approved modifications including the upgrade of C188 aircraft to Lycoming IO-720 engines, improved aerial application equipment and systems, numerous improvements to Air Tractor aircraft and recently a direct injection system for firefighting products allowing an aircraft to be filled with plain water and mix its own retardant in the hopper whilst transiting to the fire.

Pay’s pioneered the replacement of time expired spars in Air Tractor aircraft in Australia, and have a history of complete aircraft rebuilds to better than new standard. We have a large sheet metal facility, engine rebuild shop, paint shop and a large spares inventory containing almost 5000 components with a value in excess of $1.5M.



Brendon “Val” Quinell, Chief engineer/HAAMC. Val has over 54 years of aviation experience beginning in the RAAF in 1960. After his service in the Air Force Val joined QANTAS where he worked as a line engineer and eventually as a maintenance examiner on Boeing 737, 767 and 717 aircraft.

After “Retiring” in 2000 Val joined the team at Pay’s as Chief Engineer and Head of Airworthiness where he is a wealth of knowledge. Val is a private pilot and has been an aircraft owner since 1968, his current pride and joy being the Glasair III he built in 1996.

Graeme Johnston, workshop floor manager. Barra started his career with Pay’s in 1978 spending 3 years on Col Pay’s first Spitfire rebuild, following this he was heavily involved in the first Kittyhawk build. He left Pay’s in 1989 to start his own business in Wee Waa and quickly grew to operate and maintain 21 turbine Air Tractor aircraft. With combined yearly flight times averaging 21,000 hours over 17 years and zero engine failures, it is a testament to Barra’s knowledge and commitment to quality in engineering.

Barra re-joined the Pay’s team in 2006 and is now in charge of day to day running of the hangar and store. Also a private pilot and aircraft owner, he is a highly valued member of the Pay’s team.


Paint Shop

Pay’s have used an in house paint shop for all their aircraft painting requirements. All aircraft rebuilt by Pay’s since 2008 have received our in house scheme, and the number of compliments received from people far and wide is a testament to the high quality of the work performed by the paint shop.

We operate a dedicated spray booth using military spec paint, and have 2 qualified painters on staff. To organise a quote on your aircraft call Pay’s on 02 6540 1850.
