Fire and Rescue NSW (FRNSW) responded to a fire on board a small passenger aircraft, landing at Newcastle Airport at Williamtown, on Tuesday afternoon.
The pilot had sent a radio message around 12.30pm, stating that a large amount of smoke was filling the cabin.
FRNSW crews, together with the RAAF Fire Brigade, liaised with airport staff and boarded the plane after it landed safely.
The smoke was caused by a small electrical fire in the aircraft's lighting compartment.
The fire had self-extinguished.
Two crew and four passengers were assessed by Australian Defence Force medical staff and were released without injury.
NSW Police and NSW Rural Fire Service also attended the incident.
