I refer to your email of 9 December 2004 seeking an update on recommendation R20030027, which was issued to the Civil Aviation Safety Authority (CASA) in February 2003.

In an earlier response, CASA advised the Bureau that it would review the existing regulations and advisory material related to the continuing airworthiness of old wooden aircraft, including the use of casein adhesives.

Due to resourcing constraints, CASA has been unable to initiate a review of the existing regulations and advisory material, which essentially relates to older Tiger Moths and similar aircraft types that are generally used for either private flying or adventure type operations.

CASA's Aviation Safety Standards Division anticipates that a review on this issue will be completed in the first half of 2005.
