## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

AFTER TOUCHDOWN ON (KSTL) RUNWAY 30R, THE AIRPLANE VEERED TO THE LEFT WHEN THE NOSE GEAR WAS LOWERED TO THE RUNWAY AND APPLIED BRAKING ACTION. THE PILOT ATTEMPTED TO MAINTAIN DIRECTIONAL CONTROL; HOWEVER, THE AIRPLANE CONTINUED TO VEER TO THE LEFT AND DEPARTED THE RUNWAY ONTO THE GRASS. EXAMINATION OF THE AIRPLANE REVEALED THAT THE NOSE LANDING GEAR HAD COLLAPSED, AND THE ENGINE MOUNT WAS FRACTURED AT THE TWO ATTACHMENT FEET FOR THE NOSE LANDING GEAR ACTUATOR. THERE WAS ALSO ANOTHER FRACTURE OF THE LEFT LOWER FORWARD ENGINE MOUNT.

(THE PILOT DID LOST CONTROL OF N110ST, HOWEVER,):

DURING THE INVESTIGATION IT WAS DISCOVERED A PIPER MANDATORY SERVICE BULLETIN 1103F WAS ACCOMPLISHED 11/11/2015 1377.5 ACTT TO INSPECT THE ENGINE/NOSE LANDING GEAR MOUNT FOR CRACKS. THIS WAS TO BE A RECURRING INSPECTION NOT TO EXCEED EACH 100 HOURS. THERE WAS A TERMINATING ACTION OF THE SERVICE BULLETIN IF THE ENGINE MOUNT WAS REPLACED WITH AN IMPROVED NEW ENGINE MOUNT. THERE WERE NO OTHER INSPECTIONS DOCUMENTED FOR THE ENGINE/NOSE LANDING GEAR MOUNT. THE LACK OF ACCOMPLISHMENT OF PIPER SERVICE BULLETIN 1103F IS THE CAUSAL FACTOR OF THE FRACTURE AND SUBSEQUENT FAILURE TO THE ENGINE/NOSE LANDING GEAR MOUNT.
