What happened
While the specific details of the flight incident were not detailed in the provided recommendation text, the Dutch Safety Board (OVV) conducted an investigation into an Unmanned Aircraft System (UAS) occurrence. The investigation highlighted critical gaps in the information available to operators and pilots regarding the safe operation of DJI-manufactured drones, particularly concerning system behavior and emergency procedures.
The investigation
The OVV examined the operational risks associated with long-term UAS use and the reliance of private users on manufacturer-provided best practices. The investigation established that because UAS lifespans can extend far beyond their production dates, there is a significant need for continuous updates to safety guidelines. Furthermore, the Board identified a lack of timely technical support and information sharing from the manufacturer, DJI, with both safety investigation authorities and drone operators.
Findings
- The investigation identified a need for clearer instructions regarding actions to take during controllability issues, specifically when to utilize Return to Home (RTH) and Attitude (A)-mode.
- There is insufficient clarity in existing manuals regarding the specific conditions under which a compass calibration is required.
- The risks associated with integrating various payload types onto the UAS are not adequately documented.
- A lack of timely technical support from the manufacturer hinders the ability of safety investigators to conduct thorough analyses of UAS incidents.
Safety action
The Dutch Safety Board has issued formal recommendations to Da-Jiang Innovations Science and Technology Co., Ltd. (DJI) to:
- Review and update UAS user manuals and safety guidelines to include lessons learned from this incident, specifically addressing controllability, compass calibration, and payload risks.
- Ensure that both operators and safety investigation authorities are provided with necessary technical support and relevant information in a timely manner to facilitate effective accident investigations.
