The application to accomplish such retirement must be filed within five years of the original traumatic event, but the board of trustees may consider an application filed after the five-year period if it can be factually demonstrated to the satisfaction of the board of trustees that the disability is due to the accident and the filing was not accomplished within the five-year period due to a delayed manifestation of the disability or to circumstances beyond the control of the member.
Permanent and total disability resulting from a cardiovascular, pulmonary or musculo-skeletal condition which was not a direct result of a traumatic event occurring in the performance of duty shall be deemed an ordinary disability.
Before consideration of an application for accidental disability allowance by the board of trustees, the physician or physicians designated by the board shall have first made a medical examination of the member at his residence or at any other place mutually agreed upon and shall have certified to the board that he is physically or mentally incapacitated for the performance of duty, and should be retired, and the employer shall have certified to the board that the member is permanently and totally disabled as a direct result of a traumatic event occurring during and as a result of the performance of his regular and assigned duties, the time and place where the duty causing the disability was performed, that the disability was not the result of his willful negligence and that the member should be retired.
