3 INTRODUCTION This 2015 Idaho Aviation Accident Score Card (IAASC) provides details on all Idaho aircraft accidents that have occurred from January 1 to December 31, The source of data accumulated in this IAASC is compiled directly from the NTSB database. IAASC specifically includes: total number of fatal accidents, fatalities, class of aircraft, pilot qualifications, and weather conditions at the time of the accident. In addition, IAASC provides an overview of Idaho aviation safety trends while final investigations of these accidents are being conducted by the NTSB. It will be published annually during the first quarter of the following year and added to the spring issue of the Rudder Flutter. IAASC information will be discussed during Aeronautics safety and education meetings, and presented to the Division of Aeronautics Advisory Board as well as Idaho flight training organizations. IAASC is, first and foremost, a teaching tool. Pilots choosing to be safe by learning from others mistakes and avoiding risky flight operations have an above average safety record. GA flying in Idaho is as safe as the pilot chooses to make it.

4 ACCIDENT STATISTICS Comparison of 2012 and 2013 The number of aircraft crashes decreased from 39 in 2012 to 33 in The number of fatalities resulting from aircraft crashes increased from five in 2012 to 12 in The total number of fatal crashes in 2012 was five and 2013 was five. Summary of percent of total accidents and 50 percent of total fatalities in 2013 involved out of state registered aircraft. 80 percent of all aviation accidents occurred at airports with paved surface runways, while 20 percent occurred at or within close proximity to those designated as backcountry or wilderness airstrips. 25 percent of total fatalities occurred at airports with paved surface runways, while the remaining occurred at or within close proximity to those designated as backcountry or wilderness airstrips. 80 percent of total accidents in 2013 have been categorized as pilot error by the NTSB. The other 20 percent are still under investigation. The number of aviation accidents occurring in neighboring states: Wash 37 Ore. 31 Mont. 29 Nev. 29 Utah 20 Wyo. 15 Last year, on average, an aviation accident occurred every 11 days in Idaho. GENERAL AVIATION ACCIDENTS IN IDAHO In 2013 there were 33 general aviation accidents in Idaho with 12 fatalities in 5 fatal accidents, a 40 percent increase from the year before. The majority of non fatal accidents took place on non commercial fixed wing flights, the largest segment of U.S. general aviation, accounting for 78 percent of all GA accidents in Idaho and 100 percent of fatal accidents in *Percentages are based only on those accident investigations that are complete and assigned a Probable Cause by the NTSB 1

5 GA Accidents in 2013 Non Commercial Fixed Wing Commercial Fixed Wing Non Commercial Rotor Wing Commercial Rotor Wing Total Accidents Number of Aircraft* Fatal Accidents Fatalities *Each aircraft involved in a collision counted separately GA Accidents in Idaho Accidents Fatal Accidents Fatalities Fixed Wing Accidents: Summary and Comparison The causes of general aviation accidents may be grouped into three categories for analysis: 1. Pilot Related accidents occurring from the improper actions or inactions of the pilot. 2. Mechanical/Maintenance accidents occurring from mechanical failure of a component or an error in maintenance. 3. Other/Unknown i.e. pilot incapacitation and accidents with an undetermined cause according to the NTSB. In 2013, pilot related causes led to the vast majority of accidents. Nearly 80 percent of the 33 accident investigations are complete. Of those pilot related accidents, 35 percent occurred during the landing 2

6 phase of flight, 27 percent occurred during the take off phase, 15 percent occurred during the approach phase, 4 percent during cruise and 4 percent during the standing phase. Non Commercial Fixed Wing Accidents The number of accidents decreased by 15 percent in 2013, however, fatal accidents remained the same as the previous year at five. Without reliable estimates of flight activity, it s impossible to assume whether these indicate potential changes in the safety record. Nationally, we see greater than 70 percent were attributed to pilot related reasons, and less than 15 percent to documented mechanical/maintenance failures. During 2013, 100 percent of the completed investigations were attributed to pilot related errors. Flight Conditions Only six percent of all accidents occurred in instrument meteorological conditions (IMC), but these accidents accounted for 25 percent of the fatal accidents. Fifty percent of the accidents occurring in IMC were fatal compared to 75 percent of the fatal accidents that occurred in visual meteorological conditions (VMC) during daylight hours. There were no fatal accidents that occurred during night VMC. However, since the majority of all accidents (over 78 percent) took place in daytime VMC, it still accounted for 80 percent of all the fatal accidents and 75 percent of individual fatalities. Accident Causes Most pilot related accidents identify specific failures of flight planning or decision making or the characteristic hazards of high risk phases of flight. Six major categories of pilot related accidents frequently account for the largest number of accidents overall. Mechanical failures and rare occurrences such as taxi collisions, and items being overlooked as a result of an inadequate preflight inspection, make up much of the rest.

8 Pilot Qualifications Nationally, around 50 percent of all accident flights, fatal and non fatal alike were commanded by private pilots. Flights commanded by private pilots were fatal over 50 percent more often than those flights commanded by Airline Transport Pilots (ATP). The following chart shows the number of Idaho accidents, pilot s certificate level and pilot flight hours. > Pilot flight Time < Accidents None CFI ATP Commercial Private Sport Student 5

9 Aircraft Class Nationally, around 72 percent of accident aircraft were single engine, fixed gear (SEF) airplanes, which were involved in over 50 percent of all fatal accidents. The following chart illustrates that approximately two thirds of all accidents in Idaho during 2013 involved SEF airplanes. Aircraft Class (Idaho 2013) Single Engine Fixed Gear (SEF) SEF Tailwheel Single Engine Retractable Gear 2 Single Engine Turbine 3 Multi Engine Multi Engine Turbine 11 Rotary Wing Amateur Built and Experimental Light Sport Aircraft Nationally, there was a 25 percent decrease in the amount of amateur built and experimental light sport aircraft accidents. There was a 40 percent decrease in Idaho. All four amateur built accidents involved piston singles and the majority of the accident aircraft were in the landing phase of flight. There was one fatal accident with one fatality. Accident Case Study WPR13LA419 Piper PA60 602P 2 Uninjured, 1 Minor Injury History of Flight The flight departed the Provo Municipal Airport, Provo, Utah, about 0600 mountain daylight time, with SZT (Sandpoint) as its destination. On approach, the pilot requested and was approved for the GPS approach for runway 01. After descending from the clouds at about 2,500ft above ground level, the pilot received local automated weather. The winds at the time were reported from the south at 4 knots. The pilot stated he was on a right base for landing runway 01. The pilot considered the tailwind minimal for a 5,500 ft runway. The Piper landed long on runway 01 and subsequently ran off the end of the runway and impacted the localizer before coming to rest. 6

10 Weather Visual meteorological conditions prevailed for the corporate cross country flight. Winds at SZT were reported to be from 190 degrees at 4 knots. Probable Cause The pilot s failure to fly the approach at the appropriate landing speed and attain the correct touchdown point resulted in a runway overrun. Safety Comments Most landing accidents are survivable unless the aircraft collides with a fixed object. It was reported that the approach speed over the threshold was approximately 42 knots fast and the tailwind was about 10 knots. This was a preventable accident if the pilot flew a stabilized approach into the wind. Early recognition to abort is paramount and requires instinctive action by the pilot. You must abort the landing early if you cannot land on speed, on aim point, and within the first third of the runway. Trends This IAASC identifies that the majority of Idaho accidents occurred during the takeoff and landing phases of flight. These findings identify loss of control as a trend in Idaho for NTSB FINDINGS In January 2015, the NTSB posted their Most Wanted list of transportation safety improvements. These are the problem areas that we need to focus on in order to reduce accidents and save lives. It is quoted by the NTSB that while airline accidents have become rare in the U.S., pilots of non airline flights and their passengers still die by the hundreds in general aviation (GA)accidents every year due to pilot loss of control. These accidents can be reduced through ongoing pilot education, flight currency, self assessment, and vigilant situational awareness in the cockpit. The NTSB s Most Wanted List highlights safety issues identified from the NTSB s accident investigations to increase awareness about the issues and recommended safety solutions ( SUMMARY In Idaho there was a 15 percent reduction in GA accidents in While adverse weather did not cause a high number of accidents in 2013, in those accidents where weather was a primary causal factor, the fatality rate was 100 percent. A pilot s loss of control during takeoff and landing was the leading cause of accidents in Idaho during
