(Tty) acft crashed during landing. (.19) on August 5, 1999, at 2015 hours pacific daylight time, a Piper PA-28-140, N6814W, lost control during final approach and subsequently veered off the runway at the New Coalinga Municipal Airport, Coalinga, California. The aircraft, rented from and operated by a private individual, was substantially damaged. Neither the commercial rated certified flight instructor nor the student pilot were injured. The local instructional flight was conducted under the provisions of 14 CFR part 91 and originated from the Coalinga airport about 1915. Visual meteorological conditions prevailed and no flight plan was filed. The flight instructor reported that he and the student pilot were practicing a simulated forced landing to runway 30. He stated that there was a strong gusty crosswind from the right, although the automated weather observation service (AWOS) on the field was reporting calm winds. He reported that the three windsocks on the airport also indicated calm winds. About 75 to 100 feet AGL, the flight instructor noted that the student was suddenly having difficulty controlling the aircraft with the wind conditions so he took the controls from the student. About 30 to 50 feet AGL, the flight instructor applied power to go around. He stated that the engine coughed once then quit. The airplane impacted the ground about 700 feet from the approach end of runway 30, then veered left approximately 30 degrees off the runway heading and collided with the precision approach path indicator (PAPI) lights. The flight instructor reported that he steered the airplane to avoid a culvert to their left and stated that there were no toe brakes available on the his side in the cockpit. The airplane came to rest about 1,500 feet from the approach end of runway 30. The flight instructor reported that he had not experienced any problems with the aircraft or engine prior to the accident. He also reported that he did not notice any other aircraft flying around the airport at the time of the accident. A federal aviation administration inspector from the fresno, California, flight standards district office examined the aircraft after the accident. He reported that he did not find any mechanical problems with the engine or aircraft. (.4)during prior portions of the flight, the flight instructor observed that there was a strong crosswind from 330 degrees at 10 knots at pattern altitude, while the ASOS and windsocks were showing calm winds on the surface. The instructor and student then initiated a simulated forced landing to runway 30. On final approach, the student was adequately correcting for the crosswind until the airplane descended through 150 feet AGL where they experienced a wind shear and the student had difficulty controlling the airplane. About 40 to 60 feet AGL, the flight instructor took over the flight controls and initiated a go-around, but the airplane touched down hard on the runway and drifted left off the pavement. The flight instructor maneuvered the airplane further left to avoid a concrete pipe culvert and then collided with the PAPI lights. The airplane came to rest about 1,500 feet from the approach end of the runway. He reported that he had not experienced any problems with the aircraft or engine prior to the accident. Postcrash examination did not reveal any mechanical problems with the engine or airframe. (-23) the instructor and his student were on a local instructional flight at the Coalinga, CA. Airport. After performing ground reference manuevers, they returned to the airport for simulated emergency engine out landing practice. On the first attempt the student was having a difficult time with the wind. The instructor took over and attempted a go around. The engine coughed and would not come up to full power. The aircraft touched down on the left side of rwy 30 and exited the side of the runway to the west. It impacted the right PAPI light and PAPI power supply. It came to rest about 1200 ft. from touchdown and 100 ft. to the left of the runway. An examination of the airframe and engine uncovered no evidence of a mechanical malfunction.
