onsite aviation calibration

Finding an ISO/IEC 17025 accredited calibration laboratory that can provide onsite aviation calibration services is a huge convenience for any MRO or FBO. Having calibration performed on location negates the need for shipping costs and time without vital equipment. Scheduling can be very problematic when dealing with frequently used equipment. Aviation maintenance professionals often find that onsite aviation calibration is the simplest way to comply with FAA regulations and better control maintenance schedules.

However, not all onsite calibration services are the same. The core difference is whether onsite aviation calibration is performed in the hangar or a mobile calibration laboratory. Some aviation calibration labs are performing onsite calibration inside of a trailer. A mobile laboratory can allow for better environmental control, but procedures aren’t visible. When choosing onsite aviation calibration, consider the following points:


Many MROs and FBOs communicate that they have higher confidence in onsite aviation calibration work that is performed out in the open. Unfortunately, some onsite calibration providers may perform work out of view to hide disingenuous testing or repair practices. These issues are most prevalent when dealing with complex equipment, such as cabin pressure unit calibration testing or air data test set repair. A common concern is whether or not all necessary parts of complex equipment is checked. Quality and aviation maintenance professionals get a good sense of the completeness of the work when they can watch each calibrated part of the unit get tested.

External Environment Control

When performing onsite aviation calibration, technicians will ideally be able to test in a controlled environment. When a team is performing work inside the hangar, there is very little control over temperature and humidity. If calibration is performed in a trailer, the calibration technicians can keep the temperature and humidity with a certain range. Conducting work in this manner makes testing procedures more closely mirror those performed in the laboratory.


When work is performed away from the quality and aviation maintenance team, there are less opportunities to ask the calibration technicians questions. A common scenario is when equipment fails calibration testing and requires adjustment. When this occurs, maintenance personnel can benefit by talking with the calibration technician to understand the issue. If calibration is performed in the hangar, the technician can physically show maintenance professionals the causes of the failed testing.
