Nigeria’s commercial airlines have the oldest aircraft fleet in Africa, with the age of an aircraft in one of the airlines, being 28.1 years, the age many planes are either due for retirement or decommissioning or may have been retired at least some years earlier.

Dana Airlines, which started operations in November 2008, has the oldest fleet of a range of McDonnell Douglas MD-80, with one of them, still in use, 28 years and one month old.
According to data provided by planespotters.net, Dana Airlines aircraft are the grand daddies of planes plying the Nigerian skies.
At present, it operates six aircraft, all MD-80s, with the youngest delivered October 2014 and registered as 5N-BKI.
It is now 22.3 years old.
Another plane in the fleet, 5N-SAI, is 28.1 years old.

A recent study by SGI Aviation, ordered by IATA, said the average retirement age of a freighter aircraft is 32.5 years and for a passenger aircraft 25.1 years.
The study said aircraft retirements are generally governed by a number of principles.
More than half of the aircraft, which are utilised for commercial operations, are retired between 20 years and 30 years.
Freighters accounted for 17 per cent of all the commercial aircraft retirements.
Freighters tend to retire later than passenger aircraft.
It found that the average retirement age for aircraft increased from 18.8 years in 1980 to 1984 to 29.4 years in 2005 to 2009.
The retirement age dropped to 27.6 years in the last six years due to the record-high oil prices in early 2010s.
According to another report, some of the factors governing the retirement of aeroplanes are pressurisation cycles, hours of flights and fuel efficiency.
A Boeing 747 can endure about 35,000 pressurization cycles and flights — roughly 135,000 to 165,000 flight hours — before metal fatigue sets in and is retired at approximately 27 years of service, said the report written two years ago.
