MD Helicopters' sales agent in the Philippines, Asian Aerospace, could face sanctions after an investigation into the bidding process forced the defence ministry to cancel the 1.2 billion peso ($29 million) acquisition of six MD530F night-capable attack helicopters.

The investigation found "the bidding process was not properly observed" and the single-turbine MD503F did not meet the requirement for a minimum 1,360kg (3,000lb) payload. Losing bidder PZL Swidnik, which had offered the twin-turbine Kania, protested about the contract award.

The investigation report cites "an unauthorised alteration of the technical specifications". The defence ministry is investigating whether Asian Aerospace should face sanctions and whether charges should be filed against the ministry and air force officials concerned. Poland's PZL says a new tender is planned, but does not know when.
