Injuries: 3 Uninjured.
NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
The pilot reported that, while on a right base leg visual approach, he received the current automated weather report and that he did not think that the 4-knot tailwind was an issue because the runway was 5,500 feet long. The pilot reported that, although the airplane landed long, he thought that he had sufficient runway to stop the airplane with heavy braking. However, as he applied the brakes, he felt the sensation of “no brakes” as the end of the runway quickly approached. The airplane’s owner, who occupied a seat in the rear cabin, reported that the pilot seemed to be having a problem aligning the airplane with the runway during the approach, that the airplane was high and fast and the flaps were full down, and that the pilot was trying to force the airplane down onto the runway. The passenger reported that he observed that the approach speed was 132 knots; per the airplane's flight manual, the calculated approach speed for the landing weight of the airplane was about 90 knots. The airplane subsequently ran off the end of the runway and impacted the localizer structure, which resulted in substantial damage to the airplane. A postaccident examination of the airplane's braking system revealed that the brakes were likely operating properly before the airplane exited the runway.
The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot's failure to fly the approach at the appropriate landing speed and attain the correct touchdown point, which resulted in a runway overrun.
On September 23, 2013, about 0815 Pacific daylight time, a Piper PA60 602P, N35FD, sustained substantial damage as a result of a runway overrun and subsequent impact with the airport's localizer equipment at the Sandpoint Airport, Sandpoint, Idaho. The airplane was registered to Young Living Essential Oils LC, of Lehi, Utah. The commercial pilot and one passenger were not injured, while the remaining passenger sustained minor injuries. Visual meteorological conditions prevailed for the corporate cross-country flight, which was being operated in accordance with 14 Code of Federal Regulations Part 91, and an instrument flight rules flight plan was filed. The flight departed the Provo Municipal Airport, Provo, Utah, about 0600 mountain daylight time, with SZT as its destination.
In a statement submitted to the National Transportation Safety Board investigator-in-charge (IIC), the pilot reported while approaching SZT, he requested and was approved for the GPS approach [for Runway 01]. After descending out of the clouds at about 2,500 feet above ground level (agl), the pilot received the local automated weather; the wind was reported to be from 190 degrees at 4 knots. The pilot stated that as he was set up on a right base leg for runway 01, he considered the 4 knot tailwind minimal for the 5,500-foot runway. The pilot further stated that he landed quite a bit long, but thought he had sufficient room to stop with heavy braking, and [during the landing roll] had the sensation of "…no brakes at all." The airplane subsequently ran off the end of the runway, and impacted the localizer before coming to rest upright. The pilot concluded in his report that this accident could have been prevented by landing into the wind and on the numbers. The pilot reported no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
In a telephone interview with the IIC, the owner of the airplane reported that he was seated in the rear cabin at the time of the accident. The owner stated that during the approach he detected that the pilot was having an alignment problem with the approach. He further reported that the pilot was high, the flaps were full down, the airspeed over the threshold was 132 knots, and that there was a tailwind of about 10 knots; the airplane flight manual states that the approach speed for the reported landing weight of 5,156 pounds and full flaps (45 degrees) would have been about 90 knots. The owner stated that over the runway threshold, the airplane dropped down then went back up, and that the pilot tried to force the airplane down. The owner added that after the airplane went off the end of the runway and came to a stop, he exited the aircraft and noticed that while the brakes were not smoking, they were hot.
A postaccident examination of the airplane's braking system was performed by a Federal Aviation Administration airworthiness inspector, on September 25, 2013. The inspector reported that an inspection of the brake reservoir revealed that all of the brake fluid was gone, however, the inside area of the reservoir was observed to be wet and shiny, indicative that there had been brake fluid present recently. Further, inspection of the brake actuators on the pilot's rudder pedals revealed that all components appeared to be working correctly. The inspector concluded that all evidence observed supports the contention that the brakes were most likely operating properly prior to the airplane leaving the runway.
SANDPOINT — A pretrial settlement agreement is being proposed to resolve a misdemeanor criminal charge against a Utah pilot who crashed a plane at Sandpoint Airport last fall.
Donald Moss Muirhead is charged with flying under the influence of prescription medication at the time of the Sept. 23 crash.
The terms of the agreement were not made public following a pretrial hearing in Muirhead’s case on Friday in Bonner County Magistrate Court. The agreement is slated for review by Judge Debra Heise, who is presiding over Muirhead’s trial on Thursday.
Muirhead, 55, of Orem, was at the controls of a Piper Aerostar 620P when he careened 600 feet off the north end of the runway and crashed into an antenna array that helps pilots make instrument landings.
Neither Muirhead nor his 61- and 39-year-old passengers were injured.
Muirhead, according to a Sandpoint Police report, blamed the crash on a mechanical issue. Witnesses, however, told police that believed Muirhead touched down on the runway too late and with too much speed, the report said.
Replacing the antenna array and attendant equipment is expected to cost about $270,000, although the system has been deemed obsolete by airport officials. The county is considering a dual-band system that will improve the localizer’s accuracy, adding about $100,000 to the cost.

Injuries: 3 Uninjured.
This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed. NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
On September 23, 2013, about 0815 Pacific daylight time, a Piper PA60 602P, N35FD, sustained substantial damage as a result of a runway overrun and subsequent impact with the airport’s localizer equipment at the Sandpoint Airport, Sandpoint, Idaho. The airplane was registered to Young Living Essential Oils LC, of Lehi, Utah. The certified commercial pilot and one passenger were not injured, while the remaining passenger sustained minor injuries. Visual meteorological conditions prevailed for the corporate cross-country flight, which was being operated in accordance with 14 Code of Federal Regulations Part 91, and an instrument flight rules flight plan was filed. The flight departed the Provo Municipal Airport, Provo, Utah, about 0600 mountain daylight time, with SZT as its destination.
In a post-accident interview with a Federal Aviation Administration aviation safety inspector, the pilot reported that on landing rollout he experienced a braking anomaly, which resulted in a runway overrun. During the overrun the airplane impacted the runway localizer array and a perimeter fence, which resulted in substantial damage to the airplane’s left wing.
The airplane was recoverd to a secured hangar for further investigation of the reported brake anomaly.

SANDPOINT — Drug test results are pending in the case of a pilot who crashed at Sandpoint Airport Monday.
According to Sandpoint Police Chief Corey Coon, urine samples from Utah resident Donald Muirhead have been sent to the lab for analysis, which should be complete in three to four weeks.
Test results will likely factor into court proceedings regarding Muirhead’s alleged involvement in an plane crash that destroyed Sandpoint Airport’s landing instruments, Coon said. Muirhead is charged with flying an airplane under the influence of narcotics — not alcohol as previously reported.
The charges are connected to the Monday airport crash, during which the Aerostar 602P piloted by Muirhead slid off the runway and into perimeter fencing at the far end of the airfield. Neither Muirhead nor his two passengers were injured in the incident. However, the collision destroyed the antenna array used by pilots to negotiate landings in darkness or bad weather.
The cost of replacing the equipment could range from $380,000 to $400,000, according to initial estimates. Furthermore, the equipment could take as long as seven months to replace due to the difficulty in acquiring and installing the appropriate instruments, according to airport manager Dave Schuck.
While global positioning systems can still be used to plan a landing in poor visibility, the ground-based antenna array allows pilots to proceed with or abandon their landing from a lower altitude, Schuck said.
The reduced airport capabilities have some officials worrying about local economic impacts. Individuals landing in Sandpoint on personal or company-owned aircraft have historically been a reliable source of revenue for local hotels, restaurants and tourist industries. In 2009, the airport’s total economic impact was estimated to be $33 million.
