If the screening window for the Hammar HIT is cracked, does that affect the PFD?

If your Hammar MA1 inflator still shows a green indicator and has no visible signs of damage, a cracked window typically won’t affect the performance of your inflatable PFD. The device should still function as intended.

However, it’s important to be aware of inspection standards. If you're stopped by authorities such as the Coast Guard, the condition of the window may be reviewed. If the crack obscures the visibility of the green indicator on the inflator face, your PFD may be considered non-compliant with Transport Canada or US Coast Guard regulations. These regulations require that the inflator’s status indicator be clearly visible through the window at all times.
