Incident at Gander Oceanic - 30 W (Conflict - potential, Conflict - loss of separation, Alleged Canadian Aviation Regulations (CARs) infraction)

Summary

2003-10-23: TSB Update - A03A0115: VVRA38 a US Navy P3 was on routing 44N 20W, 1241Z, 46N 30W, 1415Z 48N 40W 49N 50W Flight Planned Route to Brunswick NAS (KNHZ) at Flight Level 250. At 1245Z the aircraft requested and was cleared by Santa Maria to Flight Level 270. All transmissions were relayed by another aircraft (HF unserviceable). When the P3 relayed his 30W position report he was at Flight Level 290 and was requesting Flight level 310. As soon as the position report was received by Gander the aircraft was re-cleared to FL280. While at Flight Level 290 this aircraft was operating with less than the required separation of 30 Minutes longitudinally or 120 Nautical Miles lateral with two other aircraft (an AN124 and a B747). The minimum separation which occurred during the event was calculated to be 19 minutes.
