CESSNA 404       CONTINENTAL 520               Scheduled maintenance         24/09/2015                      Smoke from engine on start-up. Caused by a rag which had been inadvertently left inside the engine by a trainee engineer. Appropriate action has been taken. A pilot was asked to conduct a post-maintenance engine run follow rectification of an oil leak. Engine number one was started normally. On start of engine no.2 smoke was noted from the number 1 engine. After a short period of monitoring the pilot elected to shut down both engines and without further delay, exited the aircraft with the Fire Extinguisher and requested assistance. A fire extinguisher was discharged through the louvre at the rear of the upper engine cowling whilst another engineer gained access to the engine via the side access panel. Investigation Findings Once the engine cowling was o...

Verify correct directional travel of controls and trim                 The problem               Incorrect rigging of flight control and trim systems has led to in-flight emergencies, accidents,     and even deaths.               Four such mishaps within a 2-year span share common safety issues:    o Maintenance personnel who serviced or checked the systems did not recognize that the             control or trim surfaces were moving in the wrong direction.    o Pilots who flew the airplanes did not notice the control anomalies during their preflight                   checks.              Anyone can make mistakes. In some cases, the mechanics who performed the work   incorrectly were highly experienced. Related incident and accident...

                  In a report from the BFU  we read of a Pik 20D sailplane  which took off on aerotow behind a tug aeroplane. According to the  report, the glider pilot was unable to prevent his aircraft climbing rapidly,  so he realised he had no elevator control. He released the tow rope and  used his airbrakes in an attempt to control the aircraft’s pitch attitude  and rate of descent, but he was seriously injured in the subsequent  uncontrolled landing.                    The pilot had rigged the aircraft some 3 hours earlier, but after the wings had been attached he  connected the remainder of the parts himself. He recognised that he had forgotten to attach the  elevator connection. He did not obtain an independent check of the assembly of the aircraft or its  controls.                   T...

  ACCIDENT TO  DHRUV HELICOPTER VT-BSH   ON 19th Oct 2011  3.2. Probable Causes and Contributing Factors. 3.2.1. The cause of the accident was loss of Situational Awareness wherein the crew got Spatially Disoriented during a turn for returning to base in response to an emergency warning. In the process, the helicopter went beyond the flight envelope exceeding its structural limits and thereby leading to failure of the rotor system. 3.2.2. The contributory factors to the loss of Situational Awareness were: 3.2.2.1. Spatial Disorientation. In response to the TGB Hot Warning, the crew was required to reduce speed to 60 to 70 Kts and land as soon as possible. The Pilot initiated a manual turn without using the AFCS upper modes or reducing speed, in flight conditions below VMC. These actions coupled with inadvertent entry into clouds, led to the helicopter reaching steep nose down attitude with bank angle in excess of 90. 3.2.2.2. Pilot Training and Experie...

4. SAFETY RECOMMENDATIONS: 4.1. PHHL needs to have a comprehensive induction plan for conversion training and consolidation flying of the pilots with no previous experience on multi engine helicopters and IFR operations. 4.2. Use of simulators should be made mandatory for conversion training on ALH. 4.3. The conversion syllabus for ALH followed by HAL needs to be reviewed to accommodate the pilots from different backgrounds. 4.4. Strict monitoring of the pilot training standards should be exercised by HAL and DGCA. 4.5. Monitoring mechanism of pilots flying under Rule 160 by regulatory authority needs to be reviewed. 4.6. Pilots’ remuneration system in vogue at PHHL needs to be reviewed. It should not be linked to quantum of flying. 4.7. HAL needs to be pro-active in providing product support as manufacturer as well as maintenance/operations contractor. 4.8. Comprehensive safety audit should be carried out by trained auditors from different base or Headquarters. 4.9. HAL n...

         Three different calculations of fuel quantity information,  based on one incorrect information source  Investigation           In June 2007, a Brasilia turboprop aircraft conducting a charter flight with 31 people on board lost power from its left engine shortly before landing at its destination. The flight  crew conducted a missed approach and landed about 12 minutes later. The fuel tank supplying the left engine had no fuel remaining, and the fuel quantity  indicator was over-reading because of a mechanical defect. Other methods of  calculating the fuel quantity existed, but were not used effectively.            • The aircraft was equipped with a fuel totaliser, which would provide an indication  of the fuel consumed during a flight, but most of the operator’s flight crew obtained  the fuel consumed by calculating the difference between the ‘total fue...

    The  investigation into an aircraft’s collision with terrain in Queensland has highlighted the vital importance of avoiding fuel contamination, and the value of using all safety equipment, including shoulder harnesses, in case an accident does occur.                     On 19 June 2012, the Cessna 182P departed Mayvale Station, about 53 km from Cunnamulla, Queensland to conduct an aerial inspection of the property. The pilot, who was the only person on board, would later recall that, shortly after becoming airborne, at about 80 to 100 ft, the aircraft lost airspeed. Then, while conducting a forced landing, the aircraft clipped a tree. The next thing he could recall was being on the ground, out of the aircraft and unable to stand. The aircraft had collided with the ground and come to rest inverted.  Although the aircraft was fitted with a single shoulder strap harness, the pilot had only fastened the seat bel...

    According to the BFU  Super Dimona had completed three flights on the day and the crew was taking off on a fourth, when the nose of the aircraft reared up, accompanied by a  noise. The pitch up could not be countered by moving the control column forward, but at a height of  about 40 feet the aircraft stalled and fell to earth. The crew were fortunately uninjured.                     The elevator had become disconnected from the control linkage, and the  investigation concluded that the bolt holding the linkage together inside the tail plane had fallen out as a result of being too short for the lock nut which was fitted to it. The connection is invisible to normal daily inspections, and is apparently in an awkward position.            The investigation concluded that the bolt used for the connection was of a size approved by the manufacturer, ...

 FLAP UP - ACCIDENT                      Cessna 152 of 1980 model met an accident on Date : 21 March 2012 and get  damage: of Nose wheel collapsed, engine shock-loaded, propeller,   spinner, left wing, cockpit screen and empennage   damaged.                       Having flown one touch-and-go landing on grass  Runway , the pilot positioned the aircraft for a  second landing. He recalled that the approach had  appeared normal, but as he flared the aircraft to land it  suddenly lost height and touched down heavily on the   runway. The aircraft then bounced twice before tipping   forward until it came to rest inverted. The pilot was  uninjured and vacated the aircraft unaided through the  right window.                        The pilot stated that he ...

                      On April 11, 2005, a Cessna 152, crashed  after the rudder jammed during spin recovery training.  The CFI and the student pilot were killed, and the airplane was substantially damaged. The flight departed  about 1230  and proceeded to a practice area about 10 miles east of the airport. Witnesses reported that, while  at an altitude of about 3,000 feet above ground level, the airplane descended in a nose-down  spiral from which it did not recover and crashed into a field.                 Examination of the wreckage revealed that the rudder was jammed approximately 35°,  which is beyond its left travel limit.  Further examination revealed that the two rudder bumpers had been installed inverted and that the right rudder bumper had traveled beyond the rudder stop  and had locked behind it. the accident airplane’s right rudder...

Electrical connector in cabin heater power supply  overheated                         (15 February 2012) During the approach, wisps of smoke were seen to  come from the area of the cabin heater selector switch.  The system was isolated, the cabin fire extinguisher  was discharged and the aircraft made an uneventful  landing. The source of the smoke and acrid smell was  an overheated and partially melted electrical connector. History of the flight An instructor was conducting an instrument training  flight with one student flying the aircraft and a  passenger, who was also a student, in a rear seat  observing the flight. The student had been given  clearance for a low approach and go-around. The  aircraft was approximately six miles from Birmingham  Airport, established on the ILS for Runway 33, when  the passenger reported that there were wisps of smoke...

                                                                                            A report on an accident to a homebuilt Jabiru aircraft which suffered a jammed rudder control on landing, causing it to leave the runway surface and turn over, injuring the occupants. The jam had apparently occurred as a result of insufficient clearance between the leading edge of the rudder and the trailing edge of the fin.                  Although jamming of aircraft control surfaces is not common in flight, it can have catastrophic consequences. As the AAIB report points out, aerodynamic or inertial loads can distort aircraft skin during flight, and any possibility of such distortion causing a control jam should ...
