Narrative:
On aug/tue/89, XY31 local, kyz flight leaving mco for gnv had a right engine fire warning light illuminate. Checklists were started and the tower was notified or the emergency (an emergency was declared). When power was reduced on the right engine, the warning light extinguished and did not come back on. The emergency was cancelled with mco tower and a normal landing was completed. There were no signs of fire or smoke. I believe situations like this could be avoided if the fire detection systems in the xx aircraft were better designed. The system has a history of false indications. This could prove disastrous when pilots flying the xx aircraft transition to other aircraft. A fire warning should always be treated as an actual emergency, but in the case of the xx aircraft, one should know and understand its fire detection system. This knowledge could prevent further problems.

Title: FLT CREW OF SMT ON CLIMB OUT HAD RIGHT ENGINE FIRE WARNING. REDUCED POWER, LIGHT WENT OUT. RETURNED AND LANDED. FALSE FIRE WARNINGS ALLEGEDLY COMMON TO THIS ACFT.
Narrative: ON AUG/TUE/89, XY31 LOCAL, KYZ FLT LEAVING MCO FOR GNV HAD A RIGHT ENGINE FIRE WARNING LIGHT ILLUMINATE. CHECKLISTS WERE STARTED AND THE TWR WAS NOTIFIED OR THE EMER (AN EMER WAS DECLARED). WHEN POWER WAS REDUCED ON THE RIGHT ENGINE, THE WARNING LIGHT EXTINGUISHED AND DID NOT COME BACK ON. THE EMER WAS CANCELLED WITH MCO TWR AND A NORMAL LNDG WAS COMPLETED. THERE WERE NO SIGNS OF FIRE OR SMOKE. I BELIEVE SITUATIONS LIKE THIS COULD BE AVOIDED IF THE FIRE DETECTION SYSTEMS IN THE XX ACFT WERE BETTER DESIGNED. THE SYSTEM HAS A HISTORY OF FALSE INDICATIONS. THIS COULD PROVE DISASTROUS WHEN PLTS FLYING THE XX ACFT TRANSITION TO OTHER ACFT. A FIRE WARNING SHOULD ALWAYS BE TREATED AS AN ACTUAL EMER, BUT IN THE CASE OF THE XX ACFT, ONE SHOULD KNOW AND UNDERSTAND ITS FIRE DETECTION SYSTEM. THIS KNOWLEDGE COULD PREVENT FURTHER PROBLEMS.
