The quantity and quality of information have improved, but icing is ever a deadly foe
|Ten years ago, the National Aviation Weather Program Council met in Washington, D.C., to develop ideas that could be turned into practical steps toward reducing the number of weather-related aircraft accidents. Regarding in-flight icing, the group—which included FAA, Department of Defense, NASA, Department of Commerce, Department of Agriculture and NTSB representatives—concluded that better observation systems were needed for detecting icing, and weather forecasts should present icing hazards in clear, easily understood formats. |

Parachute Jump Operations
The risks go beyond just jumping out of an airplane
|This past September, the NTSB completed a special investigation on accidents involving aircraft used in parachute jumping. |

Take weather briefings seriously
|There’s never been so much pre- and in-flight weather information available for pilots. If you can’t gather the raw data, forecasts and current airport observations by yourself, a briefer at a Flight Service Station (FSS) can do it for you. Unfortunately, some pilots continue to experience trouble applying the wealth of data and meteorological analyses to the realities of flight.|

Dealing with electrical failure while trying to maintain aircraft control
|The NTSB doesn’t just investigate accidents; it also routinely examines incidents to determine whether they expose an underlying safety problem, which, if not addressed, could set the stage for future accidents. Recently, it examined an incident involving an Airbus A320 operated by United Airlines. This led to the discovery that there had been at least 49 similar incidents in the United States and the United Kingdom. In response to its own investigation, the NTSB issued a safety recommendation, hoping to encourage FAA action.|

Waking Up To Fatigue
Just because you’re awake, doesn’t mean you’re alert
|The FAA is paying renewed attention to human fatigue in aviation, particularly in air transport operations. This issue has troubled the NTSB to such an extent that it has appeared on its annual “Most Wanted Transportation Safety Improvements” every year since the list was first published in 1990. |

The finer points of turbocharged engine operation
|You may already fly an aircraft with a turbocharged engine. If not, and you plan on expanding your aviation horizons, there may be a turbocharger in your future. A turbocharged engine can maintain sea level manifold pressure up to critical altitude. When equipped with an automatic density controller, nearly constant horsepower will be automatically produced up to the critical altitude.|

The Accelerated Stall
Stalling at higher speeds than a normal stall
|The accelerated stall usually surprises a pilot because it occurs at a higher airspeed than a normal stall (in which a wing loading of 1 G is maintained). Remember, a wing can be made to stall at any speed—all that has to happen is for the angle of attack to get high enough. As G-loading increases, so does stall speed. If a wing reaches its critical angle of attack when the wing loading is 2 G, twice normal, the stall will occur at a speed that’s proportional to the square root of the wing loading. |

Tight Is Right
Inadequate preflights can have dire consequences
|It has been said that oil is the blood of an engine. If the oil is old and tired, contains foreign materials or flows at the wrong pressure, the engine’s optimum life span can be threatened. All pilots should know enough to check oil quality, as well as quantity, during preflight inspection. A quick peek at oil quantity marks on the dipstick isn’t enough. During preflight, you need to determine whether the oil seems suspiciously gritty, displays an unusual color or sheen, seems too thin or too thick for the ambient temperature, or has a “burnt” aroma. Inspect inside the cowling and on the ground under the engine for signs of oil leaks.|

Tiger Or Demon In Your Tank?
|Misfueling occurs when the wrong type of fuel is pumped into an aircraft’s tanks. It could be that jet fuel gets pumped instead of gasoline, gasoline instead of jet fuel, automotive gas instead of aviation gas, automotive gas containing ethanol instead of auto gas with no additives, or something else yet to be devised by a creative fueling person.|

Avoiding CFIT Incidents
Maintaining proper altitude
|The NTSB began 2008 by issuing a Safety Alert aimed at general aviation (GA) pilots. It deals with accidents involving controlled flight into terrain (CFIT) during nighttime VFR flight. The NTSB noted that some of the CFIT accidents it has investigated in recent years could have been avoided if the pilots had maintained better altitude and geographic position awareness. According to NTSB Chairman Mark V. Rosenker, “Some of the pilots involved in these accidents had many years of experience and were instrument rated, yet for some lapses in basic airmanship, they failed to maintain proper altitude.”|

Analyzing some recently investigated accident statistics
|We seem to be at the dawn of a new era of hope for general aviation’s future with the steadily increasing popularity of light-sport aircraft (LSA). For many, the light-sport license is a lower-cost entry into the pilot community. For others, the ability to use a driver’s license in lieu of an FAA medical certificate offers a way to continue flying as long as it’s possible to self-certify that there’s no medical condition that would stand in the way of safely performing light-sport pilot duties. For everyone, an LSA’s lower fuel consumption offers hope that the cost of the $50 fly-in hamburger may someday really drop back to $50—something we haven’t seen in years!|

Knowing The NOTAMs
Don’t underestimate their importance
|Accident investigators sometimes discover that pilots don’t have information contained in NOTAMs relevant to their flights. On rare occasions, even though a pilot asked for NOTAM information in a preflight briefing, the briefer accidentally omitted an item. More often, however, pilots don’t bother doing the research.|

Asking the eternal, unanswerable question
|In every accident, there’s a chain of events or conditions leading to the outcome. Break one of the links in the chain, and the accident can be avoided, at least in theory. The individual links leading to the crash of Comair flight 5191 at Lexington, Ky., on August 27, 2006, aren’t big ones like an engine failing or running out of fuel. The NTSB’s final report indicates plenty of opportunities to change the course of events. There’s almost a compulsion to ask over and over again, “what if?”|

Catastrophic Structural Failure
Focusing on maintenance programs
The overwhelming majority of airplanes have the potential to keep flying until it’s no longer economically viable to keep them in the air, provided that they’re operated within established parameters, receive regular inspections to detect problems and undergo proper preventive maintenance. When there’s a catastrophic structural failure, such as a wing falling off, it understandably attracts attention from the industry, investigators and regulators.

Overstressing The Airframe
Exercise good preflight and in-flight judgment to keep your airplane intact
Some pilots may believe that an instrument rating and a fair amount of flight time are good insurance against getting into a situation that results in losing aircraft control or exceeding an aircraft’s design stress limits. However, without a healthy amount of good preflight and in-flight judgment, along with recurrent training that includes partial panel work and unusual attitude recovery, those two things can set the stage for getting into trouble.

The Touchdown Set-Up
Be prepared for any last-minute corrections when landing
One of the really great things about most light general aviation airplanes is that they generally are highly responsive to control and power inputs, and touchdown speeds are comparatively low, making it possible to turn a sloppy approach into a relatively benign landing through some last-minute maneuvering.

You can’t always rely on air traffic control for climate briefings
While the primary duty of controllers is to separate and direct traffic, they also have a duty to help pilots avoid weather hazards. The FAA’s handbook for controllers requires them to issue pertinent information on observed and reported weather, provide radar navigation guidance and/or approve deviations around weather when requested, define where significant weather is located in relation to an aircraft, issue the level of echo intensity and help pilots figure out the best alternative routes and altitudes to avoid weather.

Grappling with gusting winds during landings
A few weeks ago, New York was experiencing an extended period of rainy weather, accompanied by what seemed like constant low overcasts, reduced visibility and winds that were designed to test the quality of airplane tiedown ropes. I was really looking forward to the break in the weather that had been forecast for the coming weekend.

Safety In Numbers
The latest NTSB statistics suggest a decrease in general aviation accidents
This past March, the National Transportation Safety Board (NTSB) released preliminary accident statistics for 2004. The numbers show a welcome overall safety trend for general aviation (GA), with total accidents going down from 1,741 in 2003 to 1,614 in 2004. The accident rate decreased from 6.77 per 100,000 flight hours in 2003 to 6.22 in 2004. That’s a drop of more than 8%.

Fill ’Er Up
Make fuel management a priority
Running out of fuel and crashing is something you might expect from an inexperienced private pilot, but not from a crew of professional pilots or even experienced pilots. Yet that was exactly the case when it came to an accident that occurred on April 8, 2003. It involved a Dassault DA-20C Fan Jet Falcon that was being vectored by ATC in instrument meteorological conditions (IMC) for another approach.
