Issues with Pratt and Whiney engines on Airbus A321neo forces Hawaiian airlines to cut buck on services. The carrier removed summer scheduled flight between San Francisco and Honolulu and a seasonal flight between Oakland, California, and Kona, Hawaii due to delay in A321neo deliveries.
The single-isle Airbus jetliners fitted with a particular version of Pratt & Whitney geared turbofan engines caused vibration in-flight and grounded from service. Almost one third of 113 Aircraft powered by Pratt and Whitney engines in operation were grounded.
Pratt & Whitney found the cause of the issues and fixed it temporarily to keep the airplanes airborne until the permanent solution is found.
Pratt & Whitney invested $10 billion and 20 years developing these geared turbofan engines from ground up to stay ahead of its competitors and power the most widely flown type of aircraft. The engines entered service in 2016, but faced with many issues and delays costing airlines, Airbus and Pratt.
Hawaiian has taken delivery of two A321neo aircraft and expects to receive nine A321neo jets by the end of the year,
