Bad vibes at Airbus engine maker Pratt
London — Pratt & Whitney is investigating incidents of excessive vibration in its engines that power Airbus SE’s A320neo aircraft, the latest in a series of problems that have plagued the new turbine, according to people familiar with the matter. The US engine maker, a unit of Farmington, Connecticut-based United Technologies, had yet to identify the cause and was assessing if there is a connection to prior design issues, the sources said, asking not to be identified as the process isn’t public. Pilots have in some instances received alerts of high vibration levels during flights. Pratt’s geared turbofan, a step-change in the efficiency of turbines for commercial aircraft, has been hit by a run of design flaws that have grounded planes, delayed deliveries and prompted hundreds of millions of dollars in compensation claims. About 10 Pratt-powered A320neos are typically grounded at one time as the manufacturer installs fixes.
