Location: Santa Monica, CA
Accident Number: WPR18LA089
Date & Time: 02/11/2018, 1258 PST
Registration: N944X
Aircraft: SHANKS V ROGER VARI EZE
Aircraft Damage: Substantial
Defining Event: Sys/Comp malf/fail (non-power)
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Personal

Analysis 

The private pilot reported that, during the landing roll, the experimental amateur-built airplane experienced a partial loss of right brake effectiveness. The pilot attempted to counter the directional control imbalance as the roll continued, but he became concerned that the airplane might run off the end of the runway and the drop-off at the end, so he applied maximum brake pressure. The airplane then veered left, departed the runway, and impacted a hangar.

Postaccident examination revealed that a slow fluid leak had developed at the inlet fitting of the right brake caliper, and the fluid level in the reservoir for the right brake master cylinder had dropped to just under half of its capacity. This leak most likely allowed air to be introduced into the system either through the fitting or the depleted brake reservoir, which resulted in reduced effectiveness of the right brake. Maintenance records indicated that the pilot replaced the hydraulic lines on the right side about 147 flight hours before the accident.

The airplane was equipped with a free-castering nosewheel and ground steering was accomplished through differential braking once rudder effectiveness diminished at lower speeds. Therefore, with the loss of braking effectiveness on one side, the pilot had limited means to effectively slow the airplane and maintain directional control once the airplane decelerated to a speed below which rudder authority was available.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
An undetected fluid leak in the right brake line, which resulted in a reduction of braking effectiveness at the right wheel and a loss of directional control during the landing roll. 

Findings

Aircraft
Landing gear brakes system - Failure (Cause)
Landing gear steering system - Failure (Cause)
Directional control - Attain/maintain not possible (Cause)

Collision during takeoff/land 

On February 11, 2018, at 1258 Pacific standard time, an experimental amateur-built Roger V Shanks (Rutan Aircraft Factory) VariEze airplane, N944X, struck a hangar during its landing rollout at Santa Monica Municipal Airport, Santa Monica, California. The private pilot and pilot-rated passenger were not injured. The airplane sustained substantial damage to the nose and canard assembly which detached from the airframe. The airplane was registered to and operated by the pilot under the provisions of Title 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed, and no flight plan had been filed. The flight departed Brackett Field Airport, La Verne, California, about 1240.

The pilot reported that the landing approach to runway 21 was uneventful, and that he landed about 100 ft beyond the runway numbers. As soon as the nosewheel touched down, the pilot applied brake pressure and the airplane began to swerve to the left. He released and reapplied brake pressure, but the airplane continued to veer left. He then proceeded to alternately cycle the brakes and right rudder as the ground roll progressed. The oscillations continued as the airplane slowed down, but aware that the terrain dropped off beyond the runway end, the pilot decided to apply full braking effort, rather than risk descending the drop-off. The airplane then veered violently to the left, crossed over the adjacent taxiway, and struck a hangar (Photo 1).

Skid marks on the runway indicated that the airplane departed the runway surface just before taxiway B2, about 500 ft short of the runway end, and 1,300 ft before the end of the runway apron where the terrain dropped away. The skid mark on the left side was darker in color and more prominent than the mark on the right (Photo 2).

Brake System

The airplane was equipped with a free-castering nosewheel, with ground steering accomplished through differential braking once rudder effectiveness diminished at lower speeds. The design did not incorporate conventional toe-brakes, but instead brake pressure was applied directly via the rudder pedals once they had been pushed beyond the pedals' rudder travel limits.

Each rudder pedal was connected via cables to combination rudder and brake bellcrank assemblies mounted on the firewall. The brake master cylinders were also mounted on the firewall and connected directly to their respective rudder bellcrank assemblies. The master cylinders contained integral reservoirs; the cylinders were the 10-35 type manufactured by Parker Corporation. Accessing the master cylinders for fluid check and service required removal of the engine cowl.

The main landing gear were equipped with conventional brake rotors and hydraulic calipers. Each wheel assembly was enclosed within a composite wheel pant, which visually obscured the caliper and brake rotor.

Postaccident examination of the brake master cylinders revealed that the right brake reservoir fluid level was filled to just under half of its capacity. Further examination revealed that the top and rear surfaces of the right caliper were coated with dirt-encrusted fluid, from a leak which appeared to have developed at the inlet fitting of the caliper (Photo 3). No active drips were observed, and examination of the remaining brake system components did not reveal any other fluid leaks or mechanical anomalies, and the left brake reservoir was full.

Maintenance records indicated that the pilot replaced the hydraulic brake lines on the right side in July 2014, 147.3 flight hours before the accident. He reported using "NylaFlow" nylon tubing, in accordance with the airframe kit manufacturers instructions, and although there was no entry in the logbooks, he also replaced the left brake lines a brief time later with the same material. He stated that the right line was replaced because a leak had developed at the fitting on the caliper, such that he found fluid on the ramp during a preflight inspection.


The pilot stated that he last checked the brake fluid reservoir levels at the most recent oil change, which according to the maintenance records, was 50.5 flight hours prior to the accident. He reported that on the morning of the accident, he had departed from two airports and tested the brakes during taxi on both occasions; the brakes performed appropriately, and no anomalies were encountered.

Flight Conducted Under: Part 91: General Aviation - Instructional 

Analysis 

During an instructional flight, the two pilots—an airline transport pilot giving instruction and a commercial pilot receiving instruction—flew to two airports and made an instrument approach at each airport. Upon returning to the pilots' home airport and while on another instrument approach, the engine lost all power. The pilot giving instruction assumed control of the airplane and made a forced landing in a school baseball field. During the forced landing, the airplane struck trees and a fence, causing substantial damage to a wing spar.

During a postaccident examination, a total of ½ gallon of fuel was drained from both tanks. The airplane's fuel capacity was 42 gallons, of which 40 gallons was usable. The airplane had been serviced with fuel several days before the accident, and the service technician estimated that 34 gallons of fuel was on board the airplane at the beginning of the accident flight. The pilot giving instruction reported that he had visually verified that the airplane was "full of fuel" before the flight, and he expected that there would be enough fuel for 4 hours of flight. The pilot giving instruction planned 3 hours of flight time, and the airplane's Hobbs meter indicated 3.1 hours of flight time.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The instructor pilot's inadequate preflight fuel planning, which resulted in fuel exhaustion and a total loss of engine power.

Findings

Factual Information

On January 24, 2018, at 1418 central standard time, a Quartz Mountain Aerospace (Luscombe) 11E, N515BW, struck trees and a fence during a forced landing following a total loss of engine power in Omaha, Nebraska. The certificated airline transport flight instructor and certificated commercial flight instructor receiving instruction were not injured. The airplane sustained substantial damage. The rental airplane was registered to and operated by Oracle Aviation, LLC, Omaha, Nebraska, and operated under the provisions of Title 14 Code of Federal Regulations Part 91 as an instructional flight. Day visual meteorological conditions prevailed, and an instrument flight rules (IFR) flight plan had been filed. The flight originated from Millard Airport (MLE), about 1100.

According to the instructor's accident report, the airplane was full of fuel (verified visually), which should have provided about four hours of flight time. The planned flight time was 3 hours. They flew to Wayne Municipal Airport (LCG), Wayne, Nebraska, and Central Nebraska Regional Airport (GRI), Grand Island Nebraska, where they made an instrument approach at each airport before returning to MLE. The airplane was on the GPS (Global Positioning System runway) 12 instrument approach, about 5.3 miles from MLE, when the engine lost power. Following the emergency checklist, the engine regained power for about 10 seconds. The instructor assumed control and made a forced landing in a school baseball field near a road intersection. During the forced landing, the airplane struck trees and a fence, causing damage to a wing spar.

The airplane was towed back to MLE where Federal Aviation Administration (FAA) inspectors from the Lincoln, Nebraska, Flight Standards District Office (FSDO) examined the airplane. They drained a total of ½-gallon of fuel from both tanks. Both the tachometer and Hobbs meter indicated a flight duration of 3.1 hours.

The instructor noted that a similar incident occurred about two weeks earlier. In that case, the pilots were able to land at the airport. No determination was made as to why the engine lost power, but the instructor surmised that either the tanks did not hold 42 gallons, or the engine was consuming a "significantly greater amount" of fuel.

According to the service technician, when he serviced the airplane a few days before the accident, and it was not full of fuel. He added fuel to a level "just above the tab portion" of the fuel neck. Using another similar airplane, the technician demonstrated to FAA inspectors how he fueled the airplane to his customary level. He then added 6 additional gallons (3 gallons per tank) to reach the full level. It was estimated about 34 gallons of fuel was on board the airplane.

According to the instructor's accident report, the airplane was full of fuel (verified visually), which should have provided about four hours of flight time. The planned flight time was 3 hours. They flew to Wayne Municipal Airport (LCG), Wayne, Nebraska, and Central Nebraska Regional Airport (GRI), Grand Island Nebraska, where they made an instrument approach at each airport before returning to MLE. The airplane was on the GPS (Global Positioning System runway) 12 instrument approach, about 5.3 miles from MLE, when the engine lost power. Following the emergency checklist, the engine regained power for about 10 seconds. The instructor assumed control and made a forced landing in a school baseball field near a road intersection. During the forced landing, the airplane struck trees and a fence, causing damage to a wing spar.

The airplane was towed back to MLE where Federal Aviation Administration (FAA) inspectors from the Lincoln, Nebraska, Flight Standards District Office (FSDO) examined the airplane. They drained a total of ½-gallon of fuel from both tanks. Both the tachometer and Hobbs meter indicated a flight duration of 3.1 hours.

The instructor noted that a similar incident occurred about two weeks earlier. In that case, the pilots were able to land at the airport. No determination was made as to why the engine lost power, but the instructor surmised that either the tanks did not hold 42 gallons, or the engine was consuming a "significantly greater amount" of fuel.

According to the service technician, when he serviced the airplane a few days before the accident, and it was not full of fuel. He added fuel to a level "just above the tab portion" of the fuel neck. Using another similar airplane, the technician demonstrated to FAA inspectors how he fueled the airplane to his customary level. He then added 6 additional gallons (3 gallons per tank) to reach the full level. It was estimated about 34 gallons of fuel was on board the airplane.
