NTO: Skydio X10 Difficult Propeller Installation - 21 November 2024

OSB Number: SOSB-24-V12

Date: 21 November 2024

Operational Impact: Some users may experience increased resistance when installing or removing propellers, which could lead to improper seating if not fully locked.

Products affected: Skydio X10 and Skydio X10D

Description, Identification, and Manifestation

Skydio X10 propellers are designed for easy installation and removal, allowing pilots to replace them as needed by pressing down on the propeller hub, twisting the base, and lifting off the propeller. In a limited batch of spare propeller kits, pilots may notice that propellers require more force than usual for both installation and removal. Higher than standard force is defined as the feeling of excess friction.

This added resistance does not affect flight safety or the functionality of the propeller, provided the propeller is fully seated. Incomplete installation may cause the propeller hub to appear locked when it is not, potentially impacting performance.

Mitigation

Skydio Actions

Skydio has changed the manufacturing process to improve tolerance control, reducing excess friction in future propeller hub assemblies.

Operator Actions

When installing or removing an X10 propeller, press down firmly on the propeller hub and apply additional force as needed to twist and release. During installation, ensure the propeller locks into place by listening for an audible click. Refer to the Inspection Procedure below for examples of a properly and improperly seated propeller.
