Planning A Successful Maintenance— Exporting & Importing Learjets

— Dave Schiver

In recent months, Duncan Aviation has performed several pre-buy evaluations that have resulted in a Learjet being either imported into or exported out of the U.S. Unique challenges always present themselves with these types of requests.

If you consult the Type Certificate Data Sheet first, you will be able to overcome many of these issues.

All Learjets, except for Models 40 & 45:

On page 33 — note 13 of A10CE (currently at Rev 57), is a list of countries, models and ECRs that are required for exporting out of the U.S. Also noted are models that require ECRs to be unmodified in order to import back into the U.S.

Model 40 & 45:

On page 13 – note 10 of T00008WI (currently at Rev 13), are lists of JAA/ EASA and non-JAA/ EASA countries and their applicable ECRs required for each model.

Additional Requirements

If there is an ECR required to import or export your Learjet into or out of the U.S, there are other issues that you need to be aware of:

1. Learjet has not sold these ECRs in the past.
2. Learjet has not supported a Road Trip or Mobile Repair Party to comply with an ECR in the past.
3. If there is an ECR involved, it MUST be complied with prior to importing or exporting your aircraft.

At this time, to comply with a necessary ECR, you are required to go to a Learjet-Owned Service Center. Duncan Aviation is working with Bombardier, through our Authorized Service Facility Agreement, to resolve this issue.

Keep in mind, when moving aircraft across country boundaries, there are usually other requirements than those stated here. Those exact requirements are determined by the destination country.

Better Calibration = Better Performance

— James Hood

One of the biggest reasons Duncan Aviation has such a good reputation for quality is tool and instrument calibration. Fortunately, Duncan Aviation has an internal “Cal Lab” team that is the calibration resource for the entire company and for many regular customers and FBOs. Everything from torque wrenches to air data units are calibrated by this team.

To maintain quality, calibration work is extremely important and Duncan Aviation technicians recommend checking the quality of your current calibrations against this seven-point checklist:

1. Turntime: Are your standard and quick turns usually met?
   
2. Records: Does your lab keep records of your calibrations?
   
3. Warranty: Does their work have a warranty?
   
4. Documentation: Is the documentation easy to understand?
   
5. Traceability: Are your tools/instruments traceable to NIST?
   
6. Services: Can your shop meet all your calibration needs?
   
7. Answers: If you have a question, will they explain until you understand?

For more information about the calibration standards Duncan Aviation recommends, call James Hood at 800.228.1836 ext. 4272. Ask him about the magical “calibrated stone!”
