Airbus A320neo household plane powered by Pratt & Whitney PW1100G engines are at present experiencing considerably greater stow charges than these powered by rival CFM Worldwide Leap-1A, evaluation of Cirium information reveals.
In complete, practically 12% of the PW1100G-powered A320neo Household fleet is saved, in accordance with the information, in comparison with 4% for the Leap-1A-powered fleet.
Furthermore, excessive stocking charges should not restricted to the A320neo household: 14% of the A220 fleet, which is just provided with P&W PW1500G engines, is at present parked, Cirium information information.
Though the information doesn’t specify the the reason why a aircraft is parked, an airline could have ceased operations, for instance, or its jets could have issues unrelated to the engines, the storage charges within the double digits, together with a thrice greater than that of its rival, ought to concern the leaders of P&W.
Anecdotal proof factors to considerably prolonged upkeep lead occasions, a scarcity of spare engines (each linked to aerospace {industry} labor and provide chain shortages), and broader sturdiness points with next-generation energy vegetation, resulting in extra frequent store visits, as largely accountable.
Cirium’s information paints an image: 147 A320neo household jets powered by PW1100Gs are in inventory, 101 A320neos and 46 A231neos, or 12% of the Neo fleet geared up with 1,228 P&W plane.
By comparability, solely 62 of the 1,473 Leap-1A-equipped A320neo household jets are idle inside a hair of greater than 4%, in accordance with Cirium information.
The distinction in stocking charges between PW1100Gs and Leap-1As is clearly illustrated by information from Indian service IndiGo: of its 138 A320neo Household plane geared up with a P&W Geared Turbofan (GTF), 34 jets, 25% are stationed, whereas its whole fleet of 105 CFM-powered examples stay in service.
In the meantime, one other Indian service, Go First Airways, has 29 of its 54 A320neos in storage, representing a parking price of 52%.
Stocking charges for the A220 fleet geared up with PW1500G engines are additionally excessive: of the roughly 250 A220s delivered, 14% or 36 plane are parked, in accordance with Cirium information.
Latvian airline Air Baltic has 10 A220s in inventory, a 3rd of its 32-person fleet; Air Tanzania has three of the 4 A220s in storage; seven of Egyptairs 12 A220s are discarded; and 6 of the 33 A220s flown by Swiss Worldwide Air Traces are saved.
Requested to remark, Swiss declined, stating: We don’t present any public data on particular upkeep areas on this context.
Nonetheless, we are able to affirm that Switzerland additionally continues to be affected by the at present decreased resilience of provide chains within the aviation {industry}, which additionally contains engines, provides the service.
Different airways declined or didn’t reply to FlightGlobal’s requests for remark.
The issue does not seem like evenly distributed: Carriers like Air Canada, Air France, Breeze Airways, Delta Air Traces, JetBlue Airways and Korean Air have all or most of their A220s in service, in accordance with Cirium information.

Though a number of components can affect excessive storage charges, some airways have particularly cited GTF upkeep points because the trigger.
Pratt & Whitney’s prolonged turnaround occasions for engine upkeep are inflicting operational disruptions for Air Baltic, Latvian carriers chief government Martin Gauss stated in late March. As a long-term associate of Air Baltic, they might not once more ship on the promise given concerning improved turnaround occasions.
Gauss added that below regular circumstances an engine might be unavailable for 60 to 90 days throughout upkeep. That timeframe could now be nearer to a yr, he stated, noting that one engine was lacking for 386 days. Gauss added that Air Baltic lacked spare elements.

U.S. discounter Spirit has additionally adjusted its schedule to account for what chief government Ted Christie in February referred to as decreased service availability with the PW1100Gs.
Pratt & Whitney continues to battle to maintain its world fleet of Neo plane as MRO capability stays constrained and engine turnaround occasions within the store have been practically thrice longer than historic averages, Christie stated. . Neo engine efficiency and gas effectivity are wonderful, however engine efficiency on the wing has as soon as once more declined. We’re working with Pratt & Whitney to discover a answer.
He stated Spirit at one level had seven A320neos parked with out serviceable engines resulting from these points. Cirium information exhibits that Spirit nonetheless has seven PW1100G-equipped A320neos in inventory, or 9% of its 75-person fleet of the sort.
In late January, Hawaiian Airways CEO Peter Ingram stated two of 18 PW1100G-powered A321neo carriers had been grounded for an prolonged interval, awaiting serviceable engines out there.
Since late final yr, we’ve encountered constraints on the supply of A321 engines, for which Pratt & Whitney’s MRO provide chain has not been in a position to preserve tempo, Ingram stated.
P&W says it expects industry-wide provide chain pressures to ease later this yr, which is able to help elevated manufacturing of recent and overhauled engines. Within the meantime, we offer direct logistical help to our suppliers and develop options to enhance engine sturdiness.
Airbus provides: “Our groups are serving to P&W establish options to help buyer fleets in service.
Engine producers have been significantly arduous hit by the provision chain and labor market disruptions skilled by the aerospace {industry} lately, with important solid and solid elements being a notable pinch level.
Castings and forgings cannot produce them quick sufficient, says Jonathan Berger, normal supervisor of Alton Aviation Consultancy. With a restricted variety of elements out there, engine producers should select between sending elements to upkeep retailers or utilizing them to provide the brand new engines that Airbus and Boeing badly must help greater manufacturing ranges.
Completely satisfied particular person. This implies delayed deliveries. This implies very lengthy turnaround occasions within the [maintenance] shops, says Berger.
However one other issue is at play. Some airways could discover that Leap and GTF engines require extra upkeep than earlier engine fashions.
GE Aerospace has acknowledged this. In March, its VP of Engineering Mohamed Ali stated: Because it stands, Leap has a scarcity of time on the wing, particularly within the Center East and India. He cited sturdiness points with a small handful of elements.
Nonetheless, the producer is engaged on updates and claims that the Leap is extra sturdy than the CFM56 on the similar stage of program life.
At an aerospace convention in February, guide Kevin Michaels of AeroDynamic Advisory described the issues CFM and P&W perceived as start-up issues.
Seems the Leap will not be on the wing so long as the CFM56. And the turbofan, oh boy, that has its personal points, he stated.
