PMAs on leased aircraft – the call for the Age of Enlightenment
The utilization of alternative aircraft parts and components has been always one of the most disputable issues in the industry. At the time when the aircraft maintenance, repair and overhaul (MRO) industry is becoming less and less similar to what it used to be and the new technologies are penetrating every aspect of aircraft maintenance, the market is also being increasingly supplemented with new players making the PMA-dilemma even more multi-sided. With this in mind, industry experts are puzzled with the question of what influences the perception of leasing companies which are to own half of the world’s fleet by the end of the decade.
PMAs
Today PMA parts account for approx. 3-4% of the world’s spare parts market. The market share occupied by the providers of such parts has the potential to increase even further should airlines continue the liberalization of their supply chain strategies thus becoming more and more open to available alternatives.
According to Tadas Goberis, the CEO of AviaAM Leasing, during the last 10-15 years the role of PMA-parts in the aircraft aftermarket has been constantly rising. ‘It is widely believed that the main airlines’ concern regarding PMAs is their safety. But it’s not. First of all, PMA-alternatives are mostly non-critical aircraft parts. Secondly, they are fully certified by FAA and EASA and have a proven history of reliability accumulated through the utilization by major Western carriers. Moreover, the U.S. and European aviation authorities are no longer the only CAAs in the world which approve PMAs, meaning that such parts are steadily moving towards the point of universal acceptance,” commented T. Goberis.
Today PMA parts are being manufactured for almost every ATA chapter on the aircraft. According to PMA-manufacturers, the use of such parts facilitates up to30-50% cost-savings which can translate in as much as $100.000 per shop visit. Considering the fact that engine maintenance accounts for the majority of all MRO related costs, there is no wonder that today approx. 55% of the entire PMA market accounts for engine-related parts alone.
The role of lessors

The call for Enlightenment
While evaluating the market price of an asset, the owner considers 4 main factors: market strength of an aircraft type, econometric indeces, technical condition and the age of a particular aircraft. The latter, in the majority of cases, corresponds to 2/3 of the aircraft market value. Thus, from a technical point of view, PMA is not a major factor.
But it is an important issue when it comes to airlines. Carriers around the globe are still rather sceptical about PMAs and DER-repairs, particularly in the emerging markets, where such alternatives are being commonly considered as counterfeit.
One of the reasons for such a conservative perception is the lack of information and general knowledge regarding the alternatives. As a result, the PMA-history of an aircraft may force lessors to provide discounts in order to realize the asset in the market. This leads to the reduction of an aircraft’s residual value and, eventually, to a financial loss.
“Meanwhile, one should bear in mind that PMAs are mostly being utilized on 10+ years’ old aircraft. In many cases this means that PMAs are not the only alternatives to new OEM parts. There is also the growing market of dismantled parts which have less residual value-related risks. In other words, leasing companies will remain reluctant regarding the PMA usage as long as carriers worldwide remain so. One way or another, the PMA industry should be much more active, persuasive and educative if it is willing to win a bigger share in the market,” concluded the CEO of AviaAM Leasing.
