Aircraft defects may trigger rush for new brands

 AS a fallout of the suspension of B737 classics over cracks in their frames in the United States (U.S.) and Europe, and the plans by the Nigerian Civil Aviation Authority (NCAA) to follow suit, the carriers operating in Nigeria may be thrown into a fresh financial crisis when they take their Boeing 737 planes for checks due to fatigue-inducing cracks.

It was learnt that the inspection alone could cost between $350,000 and $700,000. If cracks are found, that will involve higher expenses, by having to re-skin or retrofit the plane, that is, changing the upper/outer fuselage pane.

There are indications that the new defect in Boeing may trigger a rush for other aircraft types like Embraer, Airbus A320 and others that are fuel-efficient.

Already, a new entrant into the Nigerian aviation market, First Nation Airways, has acquired nine A320, while others that are about to get their Air Operator Certificate (AOC) are said to have made orders for other aircraft brand, with the exception of Boeing classics.

In Nigeria, airlines with Boeing 737 series in their fleet are Chanchangi, Arik Air, Air Nigeria, Aero, and Skypower/Axiom Airlines.

Preliminary investigations into the U.S. accident revealed that undetected cracks widened into a five-foot hole in the roof of a Southwest Airlines flight, forcing the plane, a Boeing 737-300, to make an emergency landing at a military base from 34,000 feet.

Consequently, Boeing issued a bulletin to airlines flying some older models of its 737 jet, and called for special inspections of the lap joints in the fuselages of the planes.

Following the U.S. government's directive, all operators of the Boeing 737 series planes in Nigeria were summoned to a crucial meeting led by the Director-General, NCAA, Dr. Harold Demuren, last week.

Specifically, the U.S. airworthiness directive applies to 737s, which had flown for 30,000 cycles. The cheery news however is the fact that none of the Boeing planes in the Nigerian airline's fleet had reached 30,000 cycles except one Boeing 737-300 belonging to a cargo airline and which was grounded.

Experts in the sector have expressed worry, stressing that operators of the aircraft type in Nigeria would face huge expenses in the nearest future when the planes clocked the required 30,000 cycles.

While Chanchangi has one, Arik has two of the aircraft type and Air Nigeria has eight. Aero-contractors has five Boeing 737-500 planes and two Boeing 737-400 series; Skypower/Axiom Airlines has one. In all, over 18 aircraft face this inspection and re-skinning in the nearest future.

Another challenge before the Nigerian carrier is that as soon as the planes clock 30,000 cycles, the inspections will have to be repeated at every 500 cycles, which is at approximately four months interval.

The Head, Research and Statistics, Zenith Travels, Mr. Olumide Ohunayo, said airlines have no choice than to bear the costs.

He said the development is common with ageing planes, adding that, "they should have been ready for it long time ago."  The 737, sold in various models since 1960s, is the most popular and widely used jetliner around the world.

 

Aircraft maintenance engineer, Sheri Kyari, said the costs of inspecting and re-skinning those planes are going to be quite enormous, adding that " we don't know if Boeing will shoulder part of the costs, but everything that has to do with structures doesn't come cheap.
