Washington ( CNN ) -- Colgan Air , a regional airline , faces a nearly $ 1.9 million fine after it allegedly allowed 84 flight attendants to fly for a week after the airline was informed they had been trained on fire extinguishers that were different from those used on their aircraft . The alleged infraction occurred in November of 2009 , at a time the airline was under additional scrutiny because of a fatal crash of a Colgan Air jet near Buffalo , New York , nine months earlier . But it was unclear whether it was the additional scrutiny , or a routine inspection , that led to the discovery about the improper training . According to the Federal Aviation Administration , government inspectors discovered that new Colgan crew members were trained using a type of halon fire extinguisher found on Saab 340 aircraft , instead of the type installed on the Q400 planes they were staffing . On November 2 , 2009 , the FAA notified Colgan that crew members were not trained as required , but Colgan used the 84 untrained crew members on 172 flights during the next seven days , the FAA said . The Federal Aviation Administration on Thursday said it is proposing to fine Colgan $ 1,892,000 . Colgan said it intends to appeal the fine . `` We hope the facts presented in our response result in the proposed fine being reduced or removed , '' said Eric Epperson of Pinnacle Airlines Corp. , Colgan 's parent company . `` Colgan Air was using the same type extinguisher for both the Saab 340B and Q400 training , although the Q400 extinguisher has a hose , '' Epperson said . `` Upon notification and out of an abundance of caution , Colgan updated our training manuals and retrained all flight attendants to ensure full flight attendant understanding , '' he said . `` Safety is a top priority at Colgan . '' Colgan Air operates primarily in the northeastern United States . It operates as Continental Connection and United Express .
FAA says flight attendants quit after training on wrong extinguishers . FAA says untrained crew were used on 172 flights . Colgan plans to appeal , says it is ` ` top priority ''
