If the crew van breaks down en route to the rest facility and delays arrival for nearly 2 hours, does the flightcrew member need to notify the certificate holder?

The correct answer is based on the regulations and policies concerning crew rest requirements and the definitions of acceptable rest periods. In this scenario, if the crew member still has the opportunity to receive a full 8 hours of rest, there would be no requirement to notify the certificate holder of the delay caused by the crew van breakdown.

Regulations typically state that as long as crew members are afforded the mandated minimum rest period, they are not obligated to report the situation. The important aspect here is that the rest period is maintained regardless of the delay in transit to the rest facility.

If the crew member's rest is not compromised and they still meet the standard requirements, then there is no need for notification since their ability to perform their duties safely is not affected. This reflects a understanding of crew scheduling and the importance of the requisite rest to ensure safety and operational efficiency throughout flight operations.
