Brendan O'Hara spoke out in the House of Commons last Thursday after it was revealed that the Ministry of Defence (MOD) could be about to dispose of documents relating to the incident.
Despite a number of inquiries into the circumstances of the incident, the RAF's worst peacetime loss of life, in which 29 people were killed, no definitive answer was found as to why the helicopter crashed into the hillside near Southend.
In a letter to Defence Secretary Gavin Williamson, Mr O'Hara said: 'Given the controversy that still surrounds the cause of this tragedy, I cannot understand why the MOD would ever consider this course of action.
'There are many grieving families who are determined to get to the truth of what happened that awful evening and if they dispose of these files, the government could be destroying the only pathway to establishing the truth.'
He continued: 'As we near the 25th anniversary of the tragedy, this MOD fuelled speculation is particularly insensitive and will only cause further unnecessary pain to the families at what will be an already very difficult and emotional time.'
