Factors were fog, low ceilings, and dark night conditions. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, takeoff - initial climb - light condition - dark night (contributing factor) - weather condition - low ceiling (contributing factor) - weather condition - fog (contributing factor) - aircraft control - not maintained, pilot in command (cause) - spatial disorientation, pilot in command (cause) - use of inappropriate medication/drug, pilot in command - In flight collision with terrain/water, descent - uncontrolled ## Analysis The airplane impacted terrain during takeoff initial climb in dark night conditions with a 100 ft ceiling and 1/4 mile visibility in fog. The instrument rated private pilot sustained serious injuries and does not recall the flight. No discrepancies were found with the aircraft, flight instruments, or engines that would have contributed to the accident. A weather briefing was obtained and an IFR flight plan was filed. The pilot had 312.8 hrs total time (54.2 hrs in this aircraft), 61 hrs night flight time (36.9 hrs in this aircraft) and 26.8 hrs actual instrument time (19.6 hrs in this aircraft). Toxicological findings were positive for benzoylecgonine (metabolite of cocaine), ethanol, and cocaethylene (substance formed when cocaine and alcohol are simultaneously ingested) in a urine sample subpoenaed by the NTSB from the hospital that treated the pilot. Benzoylecgonine can be found in urine for 3 to 5 days after cocaine use. Since blood was not available for analysis, it could not be determined how much of each substance was ingested and when they were ingested. The pilot stated that he was not under the influence of cocaine or alcohol on the day of the crash. ## Factual narrative HISTORY OF FLIGHT: On November 17, 1998, at 1855 central standard time, a Cessna 414, twin engine airplane, N30ML, impacted terrain about 500 feet north of the Monroe VORTAC during takeoff/initial climb on runway 04 at the Monroe Regional Airport (MLU), Monroe, Louisiana. The airplane, owned by Sequel Group, Inc., Dallas, Texas, was operated by Just Technical Associates, Dallas, Texas, under 14 Code of Federal Regulations (CFR) Part 91. The instrument rated private pilot and the passenger received serious injuries, and the airplane sustained substantial damage. At 1853, dark night instrument meteorological conditions (IMC) with 1/4-mile visibility restricted by fog, vertical visibility of 100 feet, and a temperature and dewpoint of 13 degrees Celcius (55.4 degrees Fahrenheit) prevailed at the airport. An instrument flight rules (IFR) flight plan had been filed for the business cross country flight with a planned destination of the Love Field Airport (DAL) at Dallas, Texas. At 1813:25, the pilot telephoned De Ridder Automated Flight Service Station (AFSS). He requested and received a preflight weather briefing for an IFR flight from Monroe to Dallas, and filed the IFR flight plan. The pilot was issued a flight precaution "over [the] route for possible IFR due to stratus and fog." The weather at MLU was reported as "one mile and mist with overcast at one hundred feet." The weather at DAL was reported as "six miles and mist with overcast at nine hundred feet." The telephone briefing was concluded about 1820. At 1853:04, the MLU Air Traffic Control Tower (ATCT) Local Controller issued N30ML the following clearance: "runway four [04] turn left heading three two zero [320 degrees] cleared for takeoff runway four r v v [runway visibility value] three eighths [3/8] of a mile." After acknowledgment of the takeoff clearance, there were no further communications with the aircraft. During the takeoff roll, the controller lost sight of the aircraft in the fog. The controller heard a "loud noise" and was alerted by an Emergency Locator Transmitter (ELT) alarm about 1855 over emergency frequency 121.5 MHZ. Witnesses heard the airplane crash and saw a flash fire which extinguished before rescuers were notified. At 1900, notification was made to the local authorities. Local authorities reported that the fog reduced visibility in the area and hampered the search for the aircraft. The airplane was located at 1945. During interviews and on the Pilot/Operator Aircraft Accident Report (NTSB Form 6120.1/2), the pilot stated "I was seriously injured in the accident and I don't recall any of the details." During telephone interviews, the passenger reported that on previous business trips, he had flown with another pilot. This was the passenger's first business flight with this pilot; however, the passenger stated that this pilot "usually flew several times per month." On this flight they departed Dallas between noon and 1400. The weather at Dallas [DAL] was "very cloudy" and there were delays leaving Dallas. Upon arrival at Monroe, they obtained a rental car, went to lunch, and attended meetings for a few hours before returning to the airport for departure. The weather at the airport [MLU] was "foggy and cloudy." The passenger recalled "going down the runway, leaving the ground, and waking up days later in the hospital." In a letter dated November 23, 1999, the pilot stated that he flew the airplane with the passenger aboard from Dallas to Monroe on the morning of the accident. According to the pilot, this flight, which departed Dallas at approximately 1100, was conducted in instrument meteorological conditions and terminated with an ILS approach to runway 04 at the Monroe airport. The pilot reported that upon arrival in Monroe at approximately 1230, he and the passenger rented a car, had lunch at a restaurant, and then attended meetings. PERSONNEL INFORMATION: A review of the pilot's logbook and FAA records by the NTSB investigator-in-charge (IIC) revealed that the pilot began flight training in May 1979, and obtained his private pilot certificate in May 1980. On April 14, 1997, the pilot failed the practical examination for the addition of the multiengine rating to his private pilot certificate due to an unsatisfactory short field takeoff. The practical examination was satisfactory on April 16, 1997, and the multiengine land rating (limited to VFR only) was added to the private pilot certificate. The pilot initially flew N30ML on cross country flights under visual flight rules (VFR). The pilot added the instrument rating, airplane single engine land, on June 20, 1998, in the Cessna 172 airplane. On June 24, 1998, he added the instrument rating, airplane multiengine land, to the private certificate. The pilot's most recent third class medical certificate was issued on April 4, 1997, with a limitation to wear corrective lenses. As of November 11, 1998, the pilot's logbook records showed that he had a total of 312.8 hours flying time. The logbook indicated 61.0 hours of total night time, of which 36.9 hours were in N30ML. The pilot's actual instrument time logged was 26.8 hours, of which 19.6 hours were in N30ML. Also indicated in the logbook were 41.3 hours of time under simulated instrument conditions. The pilot's total multiengine flight time logged was 118.8 hours, of which 54.2 hours were in N30ML. The pilot had logged 1 hour of actual instrument flight time and 6.9 hours of night flight time in the 30 days before the day of the accident. AIRCRAFT INFORMATION: The aircraft (S/N 414-0005) was issued the FAA airworthiness certificate on November 26, 1969, and the aircraft was registered to the current owner on November 13, 1996. The airplane configuration included the pilot's seat, the right cockpit passenger seat, and four passenger seats in the cabin. A review of the maintenance records, by the IIC, revealed that the last annual inspection was completed on March 2, 1998, at a total aircraft time of 6,323.5 hours, and an hour meter reading of 2,304.5 hours. On October 7, 1998, the transponder and pitot static system was tested and found to comply with CFR Appendix F and E of Part 43. The hour meter reading at the accident site was 2,395.7 hours (91.2 hours since the last annual inspection). The two Teledyne Continental model TSIO-520-NCNB engines (left S/N 228405-R, right S/N 500993) were remanufactured to "Factory New Tolerances," in January 1998. The two McCauley Model 3AF32C93-JNR propellers (left S/N 682869, right S/N 745742) were overhauled in July 1998. The review of the maintenance records did not reveal any open discrepancies. METEOROLOGICAL INFORMATION: Weather reports were reviewed by the IIC. From 1235 on the day of the accident though 0900 on the following day, the National Weather Service at Monroe reported an airport visibility of 3/4 statute mile or less due to mist and/or fog. Ceilings were reported at 100 feet agl with a temperature/dewpoint spread of 1 degree or less. Both the Area Forecast for the state of Louisiana and the Terminal Forecast for Monroe, Louisiana, predicted continued instrument meteorological conditions due to mist and fog. Airmet Sierra was valid until 2100 on the day of the accident for low ceilings and visibility due to mist. AERODROME INFORMATION: The Monroe Regional Airport field elevation is 79 feet msl. The airport has 3 runways: 04/22, 18/36, and 14/32. Runway 04/22 is 7,507 feet long and 150 feet wide with an asphalt/concrete/gravel surface, with the first 6,000 feet of Runway 22 being grooved asphalt. It is equipped with high-intensity runway edge lights. The MLU VORTAC is located on the airport to the northwest side of runway 04/22. WRECKAGE AND IMPACT INFORMATION: The manufacturer representative reported that the terrain at the accident site was level and consisted of soft, wet dirt.
