What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Departed ADS approx. 1045 for destination idp on an IFR flight plan. Weather briefing obtained from 1-800-WX-brief
Departed airport and proceeded on directed heading towards Sherman. Cleared to ?7000, aircraft on autopilot at approx. 169 knots indicated airspeed. As the aircraft neared ?7000 ft altitude in moderate turbulence the horizontal situational indicator (HSI) (sandel SN3308) displayed a ?fluxgate excitation failure? Message. The pilot stated the ?HSI went red and started tumbling?. Other instruments in the aircraft seemed inoperative or unuseable. The pilot uncoupled the auto-pilot, reduced speed to approx. 120 knots, declared an emergency then went through the chute deployment procedure. The chute did not properly deploy. When the pilot realized the chute had not deployed properly he nosed the aircraft over and cleared the cloud base at approx. 1000 feet AGL. He was able to fly the aircraft back to ADS. The pilot was asked to clarify why he had made the decision to deploy the caps chute to which he replied ?because I was in hard IFR and my HSI malfunctioned?.
