Boeing 737s must be tested - But In Canada???

FAA: Boeing 737s must be tested
November 20, 2008
The Federal Aviation Administration has ordered emergency inspections of newer-generation Boeing Co. 737s, saying a fuel pump may overheat and catch fire because of improper wiring to an automatic cutoff switch.

Delta Air Lines and American Airlines are among carriers that would need to inspect 737-600, 700, 700C, 800 and 900 models under an order posted on the FAA's Web site.

The agency doesn't anticipate any airplanes will have to be grounded to comply, said Les Dorr, an FAA spokesman.

The problem, involving a fuel pump in the center wing tank, has been reported on three aircraft, the FAA said.

The wiring may cause lights to incorrectly indicate that an automatic shut-off system has stopped the pump.

About 1,490 airplanes were part of an earlier service bulletin that instructed owners to perform a certain test if they intended to install an automatic shut-off.

- Does anyone know if this AD extends to Canadian carriers operating similar aircraft ie: Sunwing and WestJet??

You can monitor the issuance of new AD's on the Continuing Airworthiness Web Information System under Recent:

CAWIS Recent

The last ADs appearing on the site right now are from yesterday (November 26th) so the new 737 AD may not have been posted yet. The site does contain the following information:

DISCLAIMER

This website provides a list of airworthiness directives (ADs), which are known to Transport Canada (TC) to be applicable to Canadian registered aircraft, and to the engines, propellers and equipment installed on them.

Aircraft owners and maintainers can be assured that this is the most comprehensive publicly available source of such information.

Additionally, TC forwards notification of all new airworthiness directives to the affected Canadian owners.

To preclude operation of an aircraft in an unairworthy condition, owners of Canadian registered aircraft should also ensure that they receive all available continuing airworthiness information directly from the manufacturer.

TC endeavours to keep this website current. However, the arrival of recently imported aeronautical products, Web posting process, etc., may result in minor delays to the information being posted.

If in doubt about the existence or applicability of any AD, please consult your local TC Inspector, or TC Aircraft Certification, Continuing Airworthiness Division in Ottawa (cawwebfeedback@tc.gc.ca).

Excellent! Thanks for the info.

A manufacturers AD applies to every aircraft built by them that is affected no matter what the country of registration.

Yeah but this isn't a Boeing AD, it's an FAA AD. There are AD's that the FAA issues that TC doesn't and therefore Canadian owner/operators can largely ignore. That being said I doubt that would happen in this case.

AD's are not issued by the manufacturer, but rather the regulatory agency who initially accepted the aircraft and assigned it a type certificate. In this case, it is the FAA.

And there are some AD's that will be specific to those being registered in a certain country, such as Canada. The one that comes to mind is the exhaust heater inspection for piston aircraft registered in Canada. A Canadian AD may also supercede a foreign AD. Careful reading is required. An example of this would be the Cessna seat rail inspection, which supercedes the US AD for the same inspection, on Canadian registered aircraft. Supposedly the manufacturer will consult on the matter, but I would bet that they have a bigger role behind closed doors of course.

Then you get into Canadian approved engines installed on foreign airframes, foreign appliances, etc, etc. It's fun for the whole family. Thankfull it is the owner's responsibility to look after it all!

Yeah, right!

If I read the AD correctly it only applies to aircraft fitted with the automatic pump shutoff. As far as I'm aware Westjet didn't buy that option.

Live long and prosper.

I stand corrected. Thanks for making me a little better informed.

FAA AD's apply to Canadian operated US built aircraft. Westjet do have some aircrfat with these type of center boost pumps.

No we don't.

Anyone from Sunwing or EnerJet able to chip in on this? And if so, does this action from the FAA affect your aircraft type?
