On 20 April 1964, while serving as a captain, he was attached to the 1/7 Gurkha Regiment as the Regimental Medical Officer in Sarawak when the helicopter he was travelling in suffered engine failure, crushing the arm of MajorEric Smith (Army officer), always known as "Birdie" Smith.[2] He amputated Smith's right arm without morphia, and stayed with Smith until they were evacuated by helicopter to Simmanggang. Despite complete exhaustion, he helped with surgery at Simmanggang and at Kuching. Crawford had already assisted six Gurkha soldiers to escape from the wreckage of the helicopter, there was a great danger of the remnants of the helicopter going up in flames, before he found Smith badly injured, trapped in the wreckage, and saved his life.[2]
