FAA Airworthiness Directive

The US FAA has released AD 2023-17-04 to address issues with gasket materials used in 'Spin-on' oil filter adters on Continental IO-360 engines. AWAL advises that the following AD is required to be complied with. Registered Operators should contact their Maintenance Provider to discuss.

Safety Advisory Notice to Yak52 Owners and Maintainers

The ATSB issued a Safety Advisory Notice to Yak52 owners and maintainers in November 2020. Albeit not the cause of the Yak52 accident off Sth Stradbroke Is, a pre-existing crack was found in the elevator bellcrank prompting the ATSB into investigating further. AWAL published this Safety Notice on Social Media and on the AWAL website. The website operates on a different platform now and some content from the old site may have been lost. Yak 52 owners and operators should familiarise themselves with the notice again and discuss the recommendations with their maintenance provider

AWAL Engineering Bulletin 22-001

With the imminent introduction of CASR 1998 Pt 43 and in line with what is regarded as the ‘norm’ in the maintenance of many GA type aircraft, AWAL has decided to introduce a planning tolerance via AWAL Engineering Bulletin EB22-001, to the periodicities stated in AWAL approved Maintenance Programs. This will be helpful in allowing continued operation when there are extended manufacturing or supply delays for parts and to provide flexibility for planning Scheduled Inspections.

T6/SNJ Wing Spar Corrosion

I would like to bring to the attention of all T6/SNJ/Havard and Wirraway owners, UK CAA AD G-2013-001. The inspection criteria of this AD is a little more comprehensive than the associated FAA AD. Corrosion has been found in an Australian registered SNJ during compliance with the UK AD. AWAL recommends owners have their Maintenance Orgs inspect their aircraft IAW the AD.

AD/PHS/10 Am2

AWAL is pleased to advise that it has negotiated an amendment to AD/PHS/10 that extends the compliance time from 6 to 12 years. This is a great outcome for our members and will save many thousands of dollars for those affected. AWAL has issued a Maintenance Direction, with some additional maintenance requirements as a blanket amendment to approved Maintenance Programs.
