Incident
at 6200N / 04000W
An American corporately registered Douglas DC3 (N45366) from Narsarsuaq, Greenland (BGBW) to Reykjavík, Iceland (BIRK) entered controlled airspace at F130 instead of F110 as cleared by Nuuk flight information centre (FIC). The aircraft was immediately re cleared to F110 due to traffic with an American corporately registered Douglas C-47A (N103NA) from Narsarsuaq, Greenland (BGBW) to Reykjavík, Iceland (BIRK) at F130.
Update TSB #A19A0030: N45366, a privately operated Douglas DC3 aircraft, was conducting an IFR oceanic crossing flight from Narsarsuaq (BGBW), Greenland to Reykjavík (BIRK), Iceland. N103NA, a privately operated Douglas C-47B aircraft, was also flying the same route. At approximate position N62°/W040°, N45366 entered controlled airspace at 13 000 feet, instead of 11 000 feet as cleared by air traffic services. In doing so, a loss of separation with N103NA occurred. The required separation is 30 minutes in trail, while the actual separation was 18 minutes.
