Several aircraft operating in Papua New Guinea, including those flown by Air Niugini, may be grounded for failing to meet requirements of the Civil Aviation Authority, or CAA.
In a move that would cripple the airline industry, Airlines PNG is seeking a judicial review of an exemption the CAA gave to other airlines from installing an Enhanced Ground Position Warning System on their aircraft.
The newspaper, The National, says the safety equipment was made compulsory for aircraft seating 30 passengers or more from last year under the Civil Aviation Act.
However, an 18-month grace period was given which meant that the ruling only became effective on July 1 this year.
The paper reports that apart from the review, Airlines PNG also wants the ruling to be applied to all airlines.
