KLM uk is carrying out an investigation following an incident on Saturday when one of its Fokker 100 aircraft carrying 78 passengers was forced to make an emergency landing at Humberside International Airport in north-east England.
The aircraft - registered as G-UKFR - was operating as UK2065 en route from Amsterdam to Aberdeen when the crew declared an emergency after noticing "a strong electrical burning smell", according to a source at KLM uk.
The two-man flight crew immediately donned breathing apparatus but there are no reports that the burning smell extended to the main cabin.
A Humberside International Airport spokeswoman adds: "Flight KLM uk 2065 diverted here at around 15:00 on 1 May after the Captain declared an emergency. The aircraft landed safely at 15:08."
The aircraft was attended to by two Humberside fire crews and three other crews from the nearby city.
All 78 passengers and five crew were unharmed and continued their journey to Aberdeen on another KLM uk aircraft that departed at 18:00.
The Fokker 100 was inspected and declared fit for service at 00:25 and returned to service the following morning.
Airclaims CASE lists the Fokker 100 as 10 years old and having 14,856h and 13,914 cycles. There are no reports of any similar electrical burning smells or any other service incidents.
A KLM uk spokesman adds: "This type of incident is extremely rare."
