ISLAMABAD, June 23: A health crisis in Pakistan International Airlines (PIA) has aggravated further after another one of its pilots suffered a heart attack, Dawn has learnt.

The PIA pilot had suffered the heart attack in Manchester on Friday afternoon. Previously, it was reported that four other PIA pilots had suffered heart attacks.

The Pakistan Airline Pilots’ Association (Palpa) had held ‘accumulated stress’ and lack of proper off days responsible for the growing number of cardiac arrests among pilots.

Civil Aviation Authority spokesman Mr Pervez George said the regulator was deeply concerned about the matter. The CAA had grounded another four pilots suspected of cardiac problems.—Staff Reporter
