Maintaining Your Aircraft Hangar Door

Here is some great advice on hangar-door maintenance from Paul at AeroDoor International. Thanks for the guest post Paul!!!


Hangar 39 Door Close UpYour hangar door is a fundamental part of your building and protects your aircraft from dust, sand and water intrusion, that’s a fact. It’s arguable that the physical condition of your hangar door can determine the success or failure of your building in extreme weather, as many buildings collapse after the hangar door has blown in.

Either way it is worth reminding you that a hangar doors condition beyond whether it opens and closes could have an impact on the doors life span, and preventive maintenance needs to be addressed.

As years pass, a once durable door that has served as the face of your aircraft hangar will begin to deteriorate due to the life expectancy of the materials and Florida's demanding climate. This can result in problems for hangar door owners that translate into much more serious and potentially dangerous or expensive scenarios that include the dreaded words “door replacement”.

Caring for your hangar door can be done through periodic service inspections and preventive maintenance, as well as following some of the simple tips below:

Bi-Fold Door Systems

  1. If sprockets have shifted, loosen mounting bolts and realign using a straight edge.
  2. If chain is loose, adjust by using the tension bolts on the gear reducer. Loose the four bolts on the back of the gear reducer, tighten the tensioning bolts until the chain has from 1/4” to 1/2” of play. Retighten all bolts and lubricate chain with oil.

Safety First

If you choose to inspect your door yourself it’s a good idea to let everyone in your hangar know that you are servicing the door and that it is not to be opened or closed by anyone until you tell them you are finished. We also advise you use the manufacturers parts or parts of equal quality.
