Aircraft manufacturer Aerospool does not make it mandatory to lock the cockpit cover, the canopy, with a safety latch and a sensor. The manufacturer is therefore missing an opportunity to increase the safety of micro light aircraft, MLAs. The Dutch Safety Board made this assessment in a follow-up memorandum in response to an earlier recommendation. The Dutch Safety Board made the recommendation to Aerospool after an accident involving an MLA in which the canopy opened during a flight.

Too much depends on choices made by pilots or flying clubs

Aerospool says it has completed all necessary steps; The manufacturer previously drew attention to safety measures in bulletins in 2008 and 2019.

The Dutch Safety Board considers this to be insufficient; As long as the locking of the canopy is not mandatory, whether or not to lock the canopy depends too much on the individual choices of pilots or owners. Aerospool should take action on the obligation itself and not wait for national aviation authorities to make such action mandatory.
