Pertubuhan Integriti dan Antirasuah Malaysia (INTRAS) has urged a comprehensive review of the Flying Doctor Service after the Sept 8 helicopter crash near Long Lellang, Ulu Baram, Sarawak, which killed a pilot and four Health Ministry personnel. Its president Datuk Mohamad Fauzi Husin said aircraft safety, maintenance standards, contractual oversight and governance must be scrutinised, including the status of other helicopters of the same type or under the same operator. INTRAS supports continuing the service for remote Sarawak communities but wants any aircraft with unresolved safety questions grounded pending inspections.
