Narrative:
After the flight crew completed the Line-up checks in preparation for departure from Warri-Osubi Airport, and while advancing the thrust levers for a short field take-off, an AgustaWestland AW139 helicopter (5N-CHO) called the TWR and reported airborne from Whiskey Alpha (WA) helipad (located 7 NM and bearing 247° M from Osubi airstrip) climbing out of 1700ft for 2500ft.
TWR cut into the transmission and called out three times, "Bravo Oscar Oscar hold position". Meanwhile, 5N-CHO continued transmitting its traffic information simultaneously until the message was completed.
At 15:23:50 h, TWR continued "Bravo Oscar Oscar hold position". In response, the crew of 5N-BOO aborted take-off at a speed of 86 knots and maximum braking was applied. The aircraft taxied back to the apron, the crew disembarked normally and discovered the left main wheel tyres (No.1 and No.2) had deflated.

Causal factor
Aborted short field take-off that necessitated the use of maximum braking which led to deflation of the left main wheel tyres (no.1 and no.2) due to lack of effective communication between the Air Traffic Control (ATC) and 5N-BOO.

Contributory factors
1. Noncompliance with NCAA audit directives by Shoreline Oil Services.
2. The absence of an established procedure to contain local traffic operating around Osubi airstrip.
