Aircraft Maintenance

Our late model aircraft participate in an extensive preventive maintenance program which minimizes the risks involved in flying in close proximity to the ground. Low altitude Pipeline Patrol operations demand the highest levels of aircraft availability and reliability. We are very proactive in our preventative maintenance philosophy which ensures the reliability and safety of the services provided by our company. Our highly maintained aircraft and experienced pilot & mechanic staff are ideal for the type of flying required in the performance of our work.

We have a full range of airframe, engine, and avionics repair capability with over 75 years of combined aircraft maintenance and repair experience and know how.

Quality aircraft maintenance is the key element in achieving our high levels of aircraft safety, reliability, and availability.

Our aircraft are maintained to the highest FAA and Manufacture  standards. We spare no expense to ensure that our aircraft are the safest and most reliable in the industry. We pride ourselves in running our Flight and Maintenance Departments with the same level of professionalism and attention to detail  as if we were a major airline.
