You are quite right, Part 25 mainly refers to new certificates.
However, in line with the amendment I had previously quoted part 121 (Amd No. 121-269) was also amended in 1998 to reflect the removal of Class D holds. As I am sure you are aware!
Final Rule Docket No. 28937 Only part 135 was finally exempted from change (Commuter/Buisness Jets). All other transport category aircraft registered after 1958 had to be upgraded to comply by 18th March 2001!
Unfortunately EASA is over a decade behind this ruling which is why some of our world colleagues are operating without fire detection. The following term of reference demonstrates the US rulings and work in progress for EASA.
ToR 26.003
FAR Part 25 Amdt 25-93 and FAR Part 121 Amdt 121-269 based on NPRM 97-10. These amendments provided the following upgrades:
— elimination of Class D cargo or baggage compartment as an option for future type certification of transport category aeroplanes;
— the Class D compartments in certain transport category aeroplanes already in service and used in passenger service must meet the fire or smoke detection and fire suppressions standards for Class C compartments;
— the Class D compartments in certain transport category aeroplanes already in service and used only for the carriage of cargo must meet the standards for Class C compartments or the corresponding standards for Class E compartments.
I hope this clarifies that US registered aircraft MUST have fire detection.
My quest is to upgrade even further and have fire suppression installed, specifically for cargo aircraft.
Class E to Class C ASAP!
