Marker Aviation Services are proud to consistently deliver customer outcomes to the highest standards.
Following are a small sample of testimonials received from our satisfied customers.

It is my great pleasure to write this testimonial for Marker Aviation. I was one of their first customers when Bill & Peter Gough set up Marker Aviation at their current location at Mount Isa airport. Bill & Peter serviced & repaired VH-PLX my Cessna 172. They helped me make the very important decision re-type, size etc. when selecting & installing a new engine in VH-PLX. This aircraft was subsequently written off in freak wind-storm at Mount Isa Airport. Bill & Peter once again assisted me when I was looking for a replacement aircraft. After serious consultation & following their & my rigours inquiries I purchased VH-DOF a Cessna 182, which they continue to service to this day. A couple of years ago, Peter & his Chief engineer Paul installed a 206 motor with a 3 bladed prop in VH-DOF. Our aircraft has never performed better. Marker Aviation also service & maintain our Bushman aircraft, a VH a registered Australian kit built. Marker Aviation have always guided me through the maze of airworthy directives advising me which directives impact my aircraft & performing the appropriate rectifications when necessary, thus ensuring that my aircraft are always properly maintained. This includes going through the lengthy process of updating VH-DOF so it is compliant with all the SID’s updates. During the entire time we have had our aircraft serviced by Marker Aviation I have gone from 100 hourly to 100 hourly with the 100% reliability. Some minor repairs were required in between these services but not foreseeable or the result of any oversights during the 100 hourly services. During our association with Marker Aviation I have seen them expand their serving capabilities to include high performance turbine aircraft, both single & twin engine in all aspects of aircraft maintenance i.e. airframe, avionics, engines. I have no reservations in recommending Marker Aviation for any servicing & or maintenance of any aircraft within their scope of operations.

I have had the privilege of working as an RFDS Medical Officer and Senior Medical Officer for past 24 years. I have worked for 3 RFDS sections during that time including Qld and South Eastern Sections and Western Operations. I have worked at the RFDS Bases in Mt Isa, Broken Hill, Charleville, Port Hedland, and Jandakot. I have worked at the Mt Isa RFDS Base since November 1997 til current. I have observed the dedication, professionalism, and absolute commitment to the Mt Isa RFDS Base that Marker Aviation has displayed over the last 20 years. Due to their dedication and willingness to repeatedly go above and beyond in their engineering support of the Mt Isa aircraft fleet that Base has a 100% online record of aeromedical availability during that period . This achievement has not been replicated in any other Qld RFDS Base. Their record of outstanding service to the RFDS commenced in 1989 and has been maintained to the current day. I am not an Engineer or Pilot and hence am not qualified to specifically assess the quality of their engineering workmanship however their record speaks for itself. I believe that the quality of their work is excellent and I have the upmost faith in their exceptional dedication to the service and to the patients of remote Australia that we serve. I have noted that Marker Aviation have also been held in high regard over many years by the state wide RFDS Aviation Maintenance Team and they are often the 'go to team' for challenging problems and challenging airframes. Only recently the Charleville B200 which had been offline for very prolonged periods of time for unscheduled maintenance was moved back to Mt Isa and there has been no recurrences of the previous issues. I have no hesitation in unreservedly endorsing Marker Aviation for aircraft maintenance & repair within their scope.
