Russian authorities are considering suspending production of the Tupolev Tu-204 and reviewing the approval of certain large General Electric and Pratt & Whitney engines.
The measures are included in a safety review disclosed by the Interstate Aviation Committee, which is also looking at the way issues with Sukhoi Superjets have been addressed.
It states that, in relation to concerns over structural defects in Tu-204 stabilisers, it will take “necessary steps” – including considering suspending the type’s certificate of production.
The Interstate Aviation Committee also says that is will examine whether to suspend validation of GE90-115B and PW4090 engines in Russia, in connection with “incidents”, without giving further details.
Both engine types are designed to power the Boeing 777.
As part of the review the Interstate Aviation Committee says it is looking into a “substantial increase” in the number of incidents involving Superjet 100s, in the context of its authority over aircraft and engine certification.
