In order for us to issue an FAA form 8110-3 with the test results several conditions must be met prior to us performing the testing. Most of the time we need in hand the following items along with the samples: An FAA project number, an FAA approved test plan that has an accompanying FAA form 8110-3, The samples with an accompanying FAA form 8130-3 showing parts conformity. As always, the FAA has the final guidance on this matter so it is best to confirm with them when the project is opened.
We normally state 5 business days. This fluctuates with how much official certification testing we have ongoing. We do not pre-schedule testing, and test in order of arrival. We do accept requests for expedited testing if needed for your program timeline.
