There was a helicopter crash in Lagos recently around Ikeja area. The sight of it caused so many awry experiences and panic to residents in that area.
So many things could have been the cause of the crash. And trust me, whatever the cause could have been avoided. In this short article, I want to let you know causes of helicopter crash and how to avoid them.
Let’s go:
Mechanical Failure: Malfunctioning components, engine problems, or structural issues can lead to a crash.
Pilot Error: Mistakes made by the pilot, such as misjudging weather conditions or navigation errors, can be a significant factor.
Weather Conditions: Severe weather, including strong winds, fog, or low visibility, can make flying challenging and increase the risk of accidents.
Collision with Objects: Helicopters can collide with birds, other aircraft, or obstacles on the ground, leading to accidents.
Human Factors: Fatigue, stress, distraction, or improper training may impair the crew’s performance and decision-making.
Fuel Issues: Running out of fuel or errors in fuel management can cause a crash.
Overloading: Carrying excessive weight beyond the helicopter’s capacity can compromise its performance.
Now, let’s discuss some solutions to mitigate these risks:
Regular Maintenance: Implement strict maintenance schedules and inspections to ensure helicopters are in optimal condition.
Pilot Training and Skill Enhancement: Provide comprehensive and continuous training to pilots to improve their skills and decision-making abilities.
Weather Monitoring: Use advanced weather forecasting systems to avoid flying in adverse weather conditions.
Improved Navigation and Communication: Enhance navigation systems and communication protocols to prevent mid-air collisions and improve coordination with air traffic control.
Bird and Obstacle Detection Systems: Install detection systems to help pilots avoid collisions with birds and other obstacles.
Human Performance Management: Implement programs to manage pilot fatigue and stress levels to maintain their cognitive abilities during flights.
Load Monitoring and Restrictions: Enforce strict weight limits and closely monitor cargo to prevent overloading.
What are the things to inspect while maintaining it?
During helicopter maintenance, there are several critical aspects that should be thoroughly inspected to ensure the aircraft’s safety and performance. Here are some key components and areas that require inspection:
Airframe: (a) Examine the entire structure of the helicopter for any signs of corrosion, cracks, or damage.
(b) Inspect the main rotor blades, tail rotor blades, and other critical parts for wear and tear.
Engine: Check the engine for proper functioning, leaks, and any signs of damage. Monitor the engine’s performance, check the oil levels, and temperature.
Avionics and Electrical Systems: Inspect all avionics equipment, instruments, and electrical systems to ensure they are functioning correctly. Verify the integrity of wiring and connections.
Transmission and Gearbox: Check the transmission and gearbox for wear, leaks, or any abnormalities. Ensure proper lubrication and functioning of these components.
Fuel System: Inspect the fuel system for leaks, blockages, and proper fuel flow. Check fuel tanks for any signs of corrosion.
Hydraulic Systems: Check hydraulic systems for leaks, proper pressure, and functioning. Pay close attention to components like hydraulic pumps and actuators.
Control Systems: Examine flight controls, including pedals, cyclic, and collective, to ensure they move smoothly without any restrictions or excessive play.
Landing Gear: Inspect the landing gear for wear, damage, and proper functioning, including shock absorbers and wheels.
Rotor Systems: Check the rotor blades for balance, tracking, and integrity. Inspect pitch links, bearings, and other rotor system components.
Emergency Equipment: Verify the functionality and expiration dates of emergency equipment like fire extinguishers, emergency locator transmitters (ELT), and first aid kits.
Cabin and Interior: Inspect the cabin for any loose or damaged items, including seats, safety belts, and emergency exits.
Logbooks and Records: Review the maintenance logbooks and records to ensure compliance with scheduled maintenance and regulatory requirements.
Proper and regular maintenance inspections are crucial to keeping helicopters in safe and airworthy condition. It’s essential to follow the manufacturer’s guidelines and regulatory requirements while conducting these inspections. Additionally, trained and qualified maintenance personnel should perform the inspections to ensure accuracy and reliability.
By addressing these factors and implementing preventive measures, the aviation industry can significantly reduce the risk of helicopter crashes and improve overall safety.
