Typical pre-delivery squawks

Fri Jun 08, 2018 2:18 pm

During pre-delivery checkouts, what's a typical squawk sheet look like? Are there ever things that trip into flight safety, or is it typically poor carpet fit and the like?

What kind of plane? Usually a variety of appearance write-ups, uncommonly more serious ones.

Was thinking mainly of airliners...

More serious ones? Do tell. Just curious as to how well the factories get them right right out of the box.

The larger airlines that have Boeings and Airbus deliveries have full time staff at the factory deliveriy centers that make sure that deliveries are not hindered by significant open issues when the customer acceptance flights are made. Delta was having serious issues with noise levels in the cabin and was considering the rejection of some of the early -800's. Not sure how that was eventually sorted out. I personally do not recall any show stoppers on the MD11 or 777 aircraft that I was involved with.

Don't know about pre-delivery squawks, but I've dealt with quite a few delivery squawks, over the years.
A couple that come to mind:
-B757 that started exhibiting external power problems. We found a pin had backed out at the external power relay.
-B757 whose auto-throttle kept disengaging. We found a wire that hadn't been crimped at the TMC.
-B747-8, we chased an HF Data problem, pretty much from day 1. Found a bad crimp in the coax.

There's a few things that crop up, but these stood out because of how long we chased them.
When seconds count...the authorities are minutes away.
Unless it's expressly prohibited, it's allowed.

By delivery, the plane is ready, flight 1 and flight 2 might be interesting. I’ve seen an engine fail to relight in-flight. An out-of-rig condition that took a few flights to get right. APU that wouldn’t start at the top of the envelope. Paint and interior issues versus “green” plane are much more common.

Galley Mats, nose wheel steering, trim and hydraulic leaks are fairly common. Those are things that are hard to be completely accurate before a plane goes through a pressure cycle. Those aren’t safety issues.

The galley mats issue is due to the plane expanding and contracting causing them to bubble up when pressurized.

Airlines customer love unresolved squawks because anything not resolved to the customers satisfaction goes to contracts and some dollar amount is deducted from the price of the aircraft. Just depends on the customer and doesn't happen very often though and usually not for anything that affects airworthiness of the aircraft.

If the customer has orders from their home office to drag their heals in accepting the aircraft because of say late financing, they sometimes will write a mountain of "chicken salad" things up.

An important variable is that the longer an airplane is in production the fewer customer write ups their will be. You might say that over time, the factory gets better at manufacturing defect free aircraft.

The WSJ did an article on this last year on a 787 delivery, if you can get through the paywall:
