About 30% of A320 Neo aircraft with P&W engines affected by glitch: Airbus
Mumbai: Low-fare airline IndiGo Monday said it has grounded three Airbus A320 Neo aircraft after its manufacturer said about 34 Neos in operations worldwide fitted with Pratt & Whitney (P&W) engines were found to have a glitch.
IndiGo has 154 aircraft, mostly A320 Neos in its fleet.
Wadia Group-run GoAir, the other Indian airline which has Neos in its fleet does not seem to be affected. Airbus said a total of 14 Neo aircraft in India are in the affected series.
“These (grounded) aircraft have both engines of the P&W series which have developed snag... Currently, the engines are being fixed and we don’t have information yet on when they can be up and running,” an IndiGo spokesperson told Mint.
Apart from halting deliveries of Neo, about 30% of A320 Neo aircraft with such engines in operation worldwide are equipped with at least one such affected engine, Airbus SE said in a statement.
The issue is different from the one faced last year, and has been identified on a limited number of recently delivered P&W GTF engines, it added.
At present, there are 113 Airbus 320 Neo aircraft with P&W engines in operations worldwide.
Some 10% of the total A320 Neos powered by P&W engines have both engines affected, Airbus said.
“This means a minimum of one engine needs to be changed on these aircraft.”
GoAir has not grounded any aircraft due to the same issue, a spokesperson of the airline said. At present GoAir has 32 Airbus aircraft in its fleet including 13 A320 Neos.
Pratt & Whitney said in a statement that it continues to evaluate the impact of the snag that came into light last week relating to a knife edge seal on the High Pressure Compressor (HPC) aft hub on a limited subpopulation of the PW1100G-JM engine that powers the Airbus A320 Neo aircraft.
“Pratt & Whitney, in coordination with Airbus, will present to regulatory authorities this week a proposed mitigation plan for the modified configuration,” the company said in a statement adding, “The company is also working to assess an overall industrial and delivery plan to minimize customer disruption.”
