In the final discover 2.5 years, IndiGo Airbus A320 Neos have on an life like seen one PW engine being changed a week. The Directorate Popular of Civil Aviation (DGCA) has in a most up-to-date RTI reply said 126 PW engines on IndiGo Neos have been replaced from 2016 to June 30, 2019.
The virtually once-a-week life like of unhealthy engine replacement comes with 46 engines being replaced in calendar years 2017 and 2018 every and 27 within the first six months of this twelve months (ultimate 7 in 2016). The reply particulars how some engines wanted to be taken off wings for replacement after flying for as much less as 37, 59 and 69 hours.
“The high quantity of engine replacement is as a result of India’s prescribing thorough (borospic) assessments of Neos’ PW engines. It is miles now not all these 126 engines were replaced after developing snags inflight or when making engaging for a flight. Many snags that led to engine replacement were printed for the duration of assessments on ground,” a senior DGCA legitimate had told TOI.
With 430 A320/21 Neos on disclose, IndiGo is the world’s very top buyer for this airplane.
