For those of you who may not see the CHIRP publication the article ended with the story of the First Officer transfering any airworthy defects from the Cabin Defect Log to the Aircraft Tech Log.
There was a defect raised by "In Charge" in the Cabin Defect Log.......
Two BCF fire extinguisers used at the rear of the aircraft.
On enquiring he discovered that there had been an oven fire but the "In Charge" decided it was not necessary to inform the flight crew!!
